NAME
       muttrc - Configuration file for the Mutt Mail User Agent

DESCRIPTION
       A mutt configuration file consists of a series of "commands".  Each
       line of the file may contain one or more commands.  When multiple
       commands are used, they must be separated by a semicolon (";").

       The hash mark, or pound sign ("#"), is used as a "comment" character.
       You can use it to annotate your initialization file. All text after the
       comment character to the end of the line is ignored.

       Single quotes ("'") and double quotes (""") can be used to quote
       strings which contain spaces or other special characters.  The
       difference between the two types of quotes is similar to that of many
       popular shell programs, namely that a single quote is used to specify a
       literal string (one that is not interpreted for shell variables or
       quoting with a backslash [see next paragraph]), while double quotes
       indicate a string for which should be evaluated.  For example, backtics
       are evaluated inside of double quotes, but not for single quotes.

       \ quotes the next character, just as in shells such as bash and zsh.
       For example, if want to put quotes (""") inside of a string, you can
       use "\" to force the next character to be a literal instead of
       interpreted character.

       "\\" means to insert a literal "\" into the line.  "\n" and "\r" have
       their usual C meanings of linefeed and carriage-return, respectively.

       A "\" at the end of a line can be used to split commands over multiple
       lines, provided that the split points don't appear in the middle of
       command names.

       It is also possible to substitute the output of a Unix command in an
       initialization file.  This is accomplished by enclosing the command in
       backquotes (`command`).

       UNIX environments can be accessed like the way it is done in shells
       like sh and bash: Prepend the name of the environment by a dollar ("$")
       sign.

COMMANDS
       alias key address [, address [ ... ]]
       unalias [ *  | key ]

              alias defines an alias key for the given addresses.  unalias
              removes the alias corresponding to the given key or all aliases
              when "*" is used as an argument.

       alternative_order type[/subtype] [ ... ]
              This command permits you to define an order of preference which
              is used by mutt to determine which part of a
              multipart/alternative body to display.  A subtype of "*" matches
              any subtype, as does an empty subtype.

       auto_view type[/subtype] [ ... ]
              This commands permits you to specify that mutt should
              automatically convert the given MIME types to text/plain when
              displaying messages.  For this to work, there must be a
              mailcap(5) entry for the given MIME type with the copiousoutput
              flag set.  A subtype of "*" matches any subtype, as does an
              empty subtype.

       bind map key function
              This command binds the given key for the given map to the given
              function.

              Valid maps are: generic, alias, attach, browser, editor, index,
              compose, pager, pgp, postpone, mix.

              For more information on keys and functions, please consult the
              Mutt Manual.

       account-hook [!]regexp command
              This hook is executed whenever you access a remote mailbox.
              Useful to adjust configuration settings to different IMAP or POP
              servers.

       charset-hook alias charset
              This command defines an alias for a character set.  This is
              useful to properly display messages which are tagged with a
              character set name not known to mutt.

       iconv-hook charset local-charset
              This command defines a system-specific name for a character set.
              This is useful when your system's iconv(3) implementation does
              not understand MIME character set names (such as iso-8859-1),
              but instead insists on being fed with implementation-specific
              character set names (such as 8859-1).  In this specific case,
              you'd put this into your configuration file:

              iconv-hook iso-8859-1 8859-1

       message-hook [!]pattern command
              Before mutt displays (or formats for replying or forwarding) a
              message which matches the given pattern (or, when it is preceded
              by an exclamation mark, does not match the pattern), the given
              command is executed.  When multiple message-hooks match, they
              are  executed  in  the order in which they occur in the
              configuration file.

       folder-hook [!]regexp command
              When mutt enters a folder which matches regexp (or, when regexp
              is preceded by an exclamation mark, does not match regexp), the
              given command is executed.

              When several folder-hooks match a given mail folder, they are
              executed in the order given in the configuration file.

       macro map key sequence [ description ]
              This command binds the given sequence of keys to the given key
              in the given map.  For valid maps, see bind.

       color object foreground background [  regexp ]
       color index foreground background [  pattern ]
       uncolor index pattern [ pattern ... ]

              If your terminal supports color, these commands can be used to
              assign foreground/backgound combinations to certain objects.
              Valid objects are: attachment, body, bold, header, hdrdefault,
              index, indicator, markers, message, normal, quoted, quotedN,
              search, signature, status, tilde, tree, underline.  The body and
              header objects allow you to restrict the colorization to a
              regular expression.  The index object permits you to select
              colored messages by pattern.

              Valid colors include: white, black, green, magenta, blue, cyan,
              yellow, red, default, colorN.

       mono object attribute [ regexp ]
       mono index attribute [ pattern ]

              For terminals which don't support color, you can still assign
              attributes to objects.  Valid attributes include: none, bold,
              underline, reverse, and standout.

       [un]ignore pattern [ pattern ... ]
              The ignore command permits you to specify header fields which
              you usually don't wish to see.  Any header field whose tag
              begins with an "ignored" pattern will be ignored.

              The unignore command permits you to define exceptions from the
              above mentioned list of ignored headers.

       lists address [ address ... ]
       unlists address [ address ... ]
       subscribe address [ address ... ]
       unsubscribe address [ address ... ]

              Mutt maintains two lists of mailing list addresses, a list of
              subscribed mailing lists, and a list of known mailing lists.
              All subscribed mailing lists are known.  A mail address matches
              a mailing list if it begins with the given address.  For
              example, the lists pattern "mutt-" will match mutt-dev@mutt.org
              and mutt-users@mutt.org.

              The lists command adds a mailing list address to the list of
              known mailing lists.  The unlists command removes a mailing list
              from the lists of known and subscribed mailing lists.  The
              subscribe command adds a mailing list to the lists of known and
              subscribed mailing lists.  The unsubscribe command removes it
              from the list of subscribed mailing lists.

       mbox-hook [!]pattern mailbox
              When mutt changes to a mail folder which matches pattern,
              mailbox will be used as the "mbox" folder, i.e., read messages
              will be moved to that folder when the mail folder is left.

              The first matchig mbox-hook applies.

       mailboxes filename [ filename ... ]
              This command specifies folders which can receive mail and which
              will be checked for new messages.  When changing folders,
              pressing space will cycle through folders with new mail.

       my_hdr string
       unmy_hdr field

              Using my_hdr, you can define headers which will be added to the
              messages you compose.  unmy_hdr will remove the given user-
              defined headers.

       hdr_order header1 header2 [ ... ]
              With this command, you can specify an order in which mutt will
              attempt to present headers to you when viewing messages.

       save-hook [!]pattern filename
              When a message matches pattern, the default file name when
              saving it will be the given filename.

       fcc-hook [!]pattern filename
              When an outgoing message matches pattern, the default file name
              for storing a copy (fcc) will be the given filename.

       fcc-save-hook [!]pattern filename
              This command is an abbreviation for identical fcc-hook and save-
              hook commands.

       send-hook [!]pattern command
              When composing a message matching pattern, command is executed.
              When multiple send-hooks match, they are executed in the order
              in which they occur in the configuration file.

       pgp-hook pattern key-id
              The pgp-hook command provides a method by which you can specify
              the ID of the public key to be used when encrypting messages to
              a certain recipient.

       open-hook regexp "command"
       close-hook regexp "command"
       append-hook regexp "command"

              These commands provide a way to handle compressed folders. The
              given regexp specifies which folders are taken as compressed
              (e.g.  "\\.gz$"). The commands tell Mutt how to uncompress a
              folder (open-hook), compress a folder (close-hook) or append a
              compressed mail to a compressed folder (append-hook). The
              command string is the printf(3) like format string, and it
              should accept two parameters: %f, which is replaced with the
              (compressed) folder name, and %t which is replaced with the name
              of the temporary folder to which to write.

       push string
              This command adds the named string to the keyboard buffer.

       set [no|inv]variable[=value] [ ... ]
       toggle variable [ ... ]
       unset variable [ ... ]
       reset variable [ ... ]

              These commands are used to set and manipulate configuration
              varibles.

              Mutt knows four basic types of variables: boolean, number,
              string and quadoption.  Boolean variables can be set (true),
              unset (false), or toggled. Number variables can be assigned a
              positive integer value.

              String variables consist of any number of printable characters.
              Strings must be enclosed in quotes if they contain spaces or
              tabs.  You may also use the "C" escape sequences \n and \t for
              newline and tab, respectively.

              Quadoption variables are used to control whether or not to be
              prompted for certain actions, or to specify a default action.  A
              value of yes will cause the action to be carried out
              automatically as if you had answered yes to the question.
              Similarly, a value of no will cause the the action to be carried
              out as if you had answered "no." A value of ask-yes will cause a
              prompt with a default answer of "yes" and ask-no will provide a
              default answer of "no."

              The reset command resets all given variables to the compile time
              defaults.  If you reset the special variabe all, all variables
              will reset to their system defaults.

       source filename
              The given file will be evaluated as a configuration file.

       unhook [ *  | hook-type ]
              This command will remove all hooks of a given type, or all hooks
              when "*" is used as an argument.  hook-type can be any of the
              -hook commands documented above.

PATTERNS
       In various places with mutt, including some of the abovementioned hook
       commands, you can specify patterns to match messages.

   Constructing Patterns
       A simple pattern consists of an operator of the form "~character",
       possibly followed by a parameter against which mutt is supposed to
       match the object specified by this operator.  (For a list of operators,
       see below.)

       With some of these operators, the object to be matched consists of
       several e-mail addresses.  In these cases, the object is matched if at
       least one of these e-mail addresses matches. You can prepend a hat
       ("^") character to such a pattern to indicate that all addresses must
       match in order to match the object.

       You can construct complex patterns by combining simple patterns with
       logical operators.  Logical AND is specified by simply concatenating
       two simple patterns, for instance "~C mutt-dev ~s bug".  Logical OR is
       specified by inserting a vertical bar ("|") between two patterns, for
       instance "~C mutt-dev | ~s bug".  Additionally, you can negate a
       pattern by prepending a bang ("!") character.  For logical grouping,
       use braces ("()"). Example: "!(~t mutt|~c mutt) ~f elkins".

   Simple Patterns
       Mutt understands the following simple patterns:

       ~A           all messages
       ~b EXPR      messages which contain EXPR in the message body
       ~B EXPR      messages which contain EXPR in the whole message
       ~c EXPR      messages carbon-copied to EXPR
       ~C EXPR      message is either to: or cc: EXPR
       ~D           deleted messages
       ~d MIN-MAX   messages with "date-sent" in a Date range
       ~E           expired messages
       ~e EXPR      message which contains EXPR in the "Sender" field
       ~F           flagged messages
       ~f EXPR      messages originating from EXPR
       ~g           PGP signed messages
       ~G           PGP encrypted messages
       ~h EXPR      messages which contain EXPR in the message header
       ~k           message contains PGP key material
       ~i EXPR      message which match EXPR in the "Message-ID" field
       ~L EXPR      message is either originated or received by EXPR
       ~l           message is addressed to a known mailing list
       ~m MIN-MAX   message in the range MIN to MAX
       ~n MIN-MAX   messages with a score in the range MIN to MAX
       ~N           new messages
       ~O           old messages
       ~p           message is addressed to you (consults $alternates)
       ~P           message is from you (consults $alternates)
       ~Q           messages which have been replied to
       ~R           read messages
       ~r MIN-MAX   messages with "date-received" in a Date range
       ~S           superseded messages
       ~s EXPR      messages having EXPR in the "Subject" field.
       ~T           tagged messages
       ~t EXPR      messages addressed to EXPR
       ~U           unread messages
       ~v           message is part of a collapsed thread.
       ~x EXPR      messages which contain EXPR in the "References" field
       ~z MIN-MAX   messages with a size in the range MIN to MAX
       ~=           duplicated messages (see $duplicate_threads)

       In the above, EXPR is a regular expression.

       With the ~m, ~n, and ~z operators, you can also specify ranges in the
       forms <MAX, >MIN, MIN-, and -MAX.

   Matching dates
       The ~d and ~r operators are used to match date ranges, which are
       interpreted to be given in your local time zone.

       A date is of the form DD[/MM[/[cc]YY]], that is, a two-digit date,
       optionally followed by a two-digit month, optionally followed by a year
       specifications.  Omitted fields default to the current month and year.

       Mutt understands either two or four digit year specifications.  When
       given a two-digit year, mutt will interpret values less than 70 as
       lying in the 21st century (i.e., "38" means 2038 and not 1938, and "00"
       is interpreted as 2000), and values greater than or equal to 70 as
       lying in the 20th century.

       Note that this behaviour is Y2K compliant, but that mutt does have a
       Y2.07K problem.

       If a date range consists of a single date, the operator in question
       will match that precise date.  If the date range consists of a dash
       ("-"), followed by a date, this range will match any date before and up
       to the date given.  Similarly, a date followed by a dash matches the
       date given and any later point of time.  Two dates, separated by a
       dash, match any date which lies in the given range of time.

       You can also modify any absolute date by giving an error range.  An
       error range consists of one of the characters +, -, *, followed by a
       positive number, followed by one of the unit characters y, m, w, or d,
       specifying a unit of years, months, weeks, or days.  + increases the
       maximum date matched by the given interval of time, - decreases the
       minimum date matched by the given interval of time, and * increases the
       maximum date and decreases the minimum date matched by the given
       interval of time.  It is possible to give multiple error margins, which
       cumulate.  Example: 1/1/2001-1w+2w*3d

       You can also specify offsets relative to the current date.  An offset
       is specified as one of the characters <, >, =, followed by a positive
       number, followed by one of the unit characters y, m, w, or d.  >
       matches dates which are older than the specified amount of time, an
       offset which begins with the character < matches dates which are more
       recent than the specified amount of time, and an offset which begins
       with the character = matches points of time which are precisely the
       given amount of time ago.

CONFIGURATION VARIABLES
       abort_nosubject
              Type: quadoption
              Default: ask-yes

              If set to yes, when composing messages and no subject is given
              at the subject prompt, composition will be aborted.  If set to
              no, composing messages with no subject given at the subject
              prompt will never be aborted.



       abort_unmodified
              Type: quadoption
              Default: yes

              If set to yes, composition will automatically abort after
              editing the message body if no changes are made to the file
              (this check only happens after the first edit of the file).
              When set to no, composition will never be aborted.



       alias_file
              Type: path
              Default: "~/.muttrc"

              The default file in which to save aliases created by the
              "create-alias" function.

              Note: Mutt will not automatically source this file; you must
              explicitly use the "source" command for it to be executed.



       alias_format
              Type: string
              Default: "%4n %2f %t %-10a   %r"

              Specifies the format of the data displayed for the `alias' menu.
              The following printf(3)-style sequences are available:

              %a     alias name


              %f     flags - currently, a "d" for an alias marked for deletion


              %n     index number


              %r     address which alias expands to


              %t     character which indicates if the alias is tagged for
                     inclusion



       allow_8bit
              Type: boolean
              Default: yes

              Controls whether 8-bit data is converted to 7-bit using either
              Quoted- Printable or Base64 encoding when sending mail.



       allow_ansi
              Type: boolean
              Default: no

              Controls whether ANSI color codes in messages (and color tags in
              rich text messages) are to be interpreted.  Messages containing
              these codes are rare, but if this option is set, their text will
              be colored accordingly. Note that this may override your color
              choices, and even present a security problem, since a message
              could include a line like "[-- PGP output follows ..." and give
              it the same color as your attachment color.



       alternates
              Type: regular expression
              Default: ""

              A regexp that allows you to specify alternate addresses where
              you receive mail.  This affects Mutt's idea about messages from
              you and addressed to you.



       arrow_cursor
              Type: boolean
              Default: no

              When set, an arrow ("->") will be used to indicate the current
              entry in menus instead of hiliting the whole line.  On slow
              network or modem links this will make response faster because
              there is less that has to be redrawn on the screen when moving
              to the next or previous entries in the menu.



       ascii_chars
              Type: boolean
              Default: no

              If set, Mutt will use plain ASCII characters when displaying
              thread and attachment trees, instead of the default ACS
              characters.



       askbcc
              Type: boolean
              Default: no

              If set, Mutt will prompt you for blind-carbon-copy (Bcc)
              recipients before editing an outgoing message.



       askcc
              Type: boolean
              Default: no

              If set, Mutt will prompt you for carbon-copy (Cc) recipients
              before editing the body of an outgoing message.



       attach_format
              Type: string
              Default: "%u%D%I %t%4n %T%.40d%> [%.7m/%.10M, %.6e%?C?, %C?, %s] "

              This variable describes the format of the `attachment' menu.
              The following printf-style sequences are understood:

              %D     deleted flag


              %d     description


              %e     MIME content-transfer-encoding


              %f     filename


              %I     disposition (I=inline, A=attachment)


              %m     major MIME type


              %M     MIME subtype


              %n     attachment number


              %s     size


              %t     tagged flag


              %u     unlink (=to delete) flag


              %>X    right justify the rest of the string and pad with
                     character "X"


              %|X    pad to the end of the line with character "X"



       attach_sep
              Type: string
              Default: "\n"

              The separator to add between attachments when operating (saving,
              printing, piping, etc) on a list of tagged attachments.



       attach_split
              Type: boolean
              Default: yes

              If this variable is unset, when operating (saving, printing,
              piping, etc) on a list of tagged attachments, Mutt will
              concatenate the attachments and will operate on them as a single
              attachment. The "$attach_sep" separator is added after each
              attachment. When set, Mutt will operate on the attachments one
              by one.



       attribution
              Type: string
              Default: "On %d, %n wrote:"

              This is the string that will precede a message which has been
              included in a reply.  For a full listing of defined
              printf()-like sequences see the section on "$index_format".



       autoedit
              Type: boolean
              Default: no

              When set along with "$edit_headers", Mutt will skip the initial
              send-menu and allow you to immediately begin editing the body of
              your message.  The send-menu may still be accessed once you have
              finished editing the body of your message.

              Also see "$fast_reply".



       auto_tag
              Type: boolean
              Default: no

              When set, functions in the index menu which affect a message
              will be applied to all tagged messages (if there are any).  When
              unset, you must first use the tag-prefix function (default: ";")
              to make the next function apply to all tagged messages.



       beep
              Type: boolean
              Default: yes

              When this variable is set, mutt will beep when an error occurs.



       beep_new
              Type: boolean
              Default: no

              When this variable is set, mutt will beep whenever it prints a
              message notifying you of new mail.  This is independent of the
              setting of the "$beep" variable.



       bounce_delivered
              Type: boolean
              Default: yes

              When this variable is set, mutt will include Delivered-To
              headers when bouncing messages.  Postfix users may wish to unset
              this variable.



       charset
              Type: string
              Default: ""

              Character set your terminal uses to display and enter textual
              data.



       check_new
              Type: boolean
              Default: yes

              Note: this option only affects maildir and MH style mailboxes.

              When set, Mutt will check for new mail delivered while the
              mailbox is open.  Especially with MH mailboxes, this operation
              can take quite some time since it involves scanning the
              directory and checking each file to see if it has already been
              looked at.  If check_new is unset, no check for new mail is
              performed while the mailbox is open.



       collapse_unread
              Type: boolean
              Default: yes

              When unset, Mutt will not collapse a thread if it contains any
              unread messages.



       uncollapse_jump
              Type: boolean
              Default: no

              When set, Mutt will jump to the next unread message, if any,
              when the current thread is uncollapsed.



       compose_format
              Type: string
              Default: "-- Mutt: Compose  [Approx. msg size: %l   Atts: %a]%>-"

              Controls the format of the status line displayed in the
              \fCompose menu.  This string is similar to "$status_format", but
              has its own set of printf()-like sequences:

              %a     total number of attachments


              %h     local hostname


              %l     approximate size (in bytes) of the current message


              %v     Mutt version string


              See the text describing the "$status_format" option for more
              information on how to set "$compose_format".



       confirmappend
              Type: boolean
              Default: yes

              When set, Mutt will prompt for confirmation when appending
              messages to an existing mailbox.



       confirmcreate
              Type: boolean
              Default: yes

              When set, Mutt will prompt for confirmation when saving messages
              to a mailbox which does not yet exist before creating it.



       connect_timeout
              Type: number
              Default: 30

              Causes Mutt to timeout a network connection (for IMAP or POP)
              after this many seconds if the connection is not able to be
              established.  A negative value causes Mutt to wait indefinitely
              for the connection to succeed.



       copy
              Type: quadoption
              Default: yes

              This variable controls whether or not copies of your outgoing
              messages will be saved for later references.  Also see
              "$record", "$save_name", "$force_name" and "fcc-hook".



       date_format
              Type: string
              Default: "!%a, %b %d, %Y at %I:%M:%S%p %Z"

              This variable controls the format of the date printed by the
              "%d" sequence in "$index_format".  This is passed to the
              strftime call to process the date. See the man page for
              strftime(3) for the proper syntax.

              Unless the first character in the string is a bang ("!"), the
              month and week day names are expanded according to the locale
              specified in the variable "$locale". If the first character in
              the string is a bang, the bang is discarded, and the month and
              week day names in the rest of the string are expanded in the C
              locale (that is in US English).



       default_hook
              Type: string
              Default: "~f %s !~P | (~P ~C %s)"

              This variable controls how send-hooks, message-hooks, save-
              hooks, and fcc-hooks will be interpreted if they are specified
              with only a simple regexp, instead of a matching pattern.  The
              hooks are expanded when they are declared, so a hook will be
              interpreted according to the value of this variable at the time
              the hook is declared.  The default value matches if the message
              is either from a user matching the regular expression given, or
              if it is from you (if the from address matches "$alternates")
              and is to or cc'ed to a user matching the given regular
              expression.



       delete
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are really deleted when closing
              or synchronizing a mailbox.  If set to yes, messages marked for
              deleting will automatically be purged without prompting.  If set
              to no, messages marked for deletion will be kept in the mailbox.



       delete_untag
              Type: boolean
              Default: yes

              If this option is set, mutt will untag messages when marking
              them for deletion.  This applies when you either explicitly
              delete a message, or when you save it to another folder.



       digest_collapse
              Type: boolean
              Default: yes

              If this option is set, mutt's revattach menu will not show the
              subparts of individual messages in a digest.  To see these
              subparts, press 'v' on that menu.



       display_filter
              Type: path
              Default: ""

              When set, specifies a command used to filter messages.  When a
              message is viewed it is passed as standard input to
              $display_filter, and the filtered message is read from the
              standard output.



       dsn_notify
              Type: string
              Default: ""

              Note: you should not enable this unless you are using Sendmail
              8.8.x or greater.

              This variable sets the request for when notification is
              returned.  The string consists of a comma separated list (no
              spaces!) of one or more of the following: never, to never
              request notification, failure, to request notification on
              transmission failure, delay, to be notified of message delays,
              success, to be notified of successful transmission.

              Example: set dsn_notify="failure,delay"



       dsn_return
              Type: string
              Default: ""

              Note: you should not enable this unless you are using Sendmail
              8.8.x or greater.

              This variable controls how much of your message is returned in
              DSN messages.  It may be set to either hdrs to return just the
              message header, or full to return the full message.

              Example: set dsn_return=hdrs



       duplicate_threads
              Type: boolean
              Default: yes

              This variable controls whether mutt, when sorting by threads,
              threads messages with the same message-id together.  If it is
              set, it will indicate that it thinks they are duplicates of each
              other with an equals sign in the thread diagram.



       edit_headers
              Type: boolean
              Default: no

              This option allows you to edit the header of your outgoing
              messages along with the body of your message.



       editor
              Type: path
              Default: ""

              This variable specifies which editor is used by mutt.  It
              defaults to the value of the VISUAL, or EDITOR, environment
              variable, or to the string "vi" if neither of those are set.



       encode_from
              Type: boolean
              Default: no

              When set, mutt will quoted-printable encode messages when they
              contain the string "From " in the beginning of a line.  Useful
              to avoid the tampering certain mail delivery and transport
              agents tend to do with messages.



       envelope_from
              Type: boolean
              Default: no

              When set, mutt will try to derive the message's envelope sender
              from the "From:" header.  Note that this information is passed
              to sendmail command using the "-f" command line switch, so don't
              set this option if you are using that switch in $sendmail
              yourself, or if the sendmail on your machine doesn't support
              that command line switch.



       escape
              Type: string
              Default: "~"

              Escape character to use for functions in the builtin editor.



       fast_reply
              Type: boolean
              Default: no

              When set, the initial prompt for recipients and subject are
              skipped when replying to messages, and the initial prompt for
              subject is skipped when forwarding messages.

              Note: this variable has no effect when the "$autoedit" variable
              is set.



       fcc_attach
              Type: boolean
              Default: yes

              This variable controls whether or not attachments on outgoing
              messages are saved along with the main body of your message.



       fcc_clear
              Type: boolean
              Default: no

              When this variable is set, FCCs will be stored unencrypted and
              unsigned, even when the actual message is encrypted and/or
              signed.



       folder
              Type: path
              Default: "~/Mail"

              Specifies the default location of your mailboxes.  A `+' or `='
              at the beginning of a pathname will be expanded to the value of
              this variable.  Note that if you change this variable from the
              default value you need to make sure that the assignment occurs
              before you use `+' or `=' for any other variables since
              expansion takes place during the `set' command.



       folder_format
              Type: string
              Default: "%2C %t %N %F %2l %-8.8u %-8.8g %8s %d %f"

              This variable allows you to customize the file browser display
              to your personal taste.  This string is similar to
              "$index_format", but has its own set of printf()-like sequences:

              %C     current file number


              %d     date/time folder was last modified


              %f     filename


              %F     file permissions


              %g     group name (or numeric gid, if missing)


              %l     number of hard links


              %N     N if folder has new mail, blank otherwise


              %s     size in bytes


              %t     * if the file is tagged, blank otherwise


              %u     owner name (or numeric uid, if missing)


              %>X    right justify the rest of the string and pad with
                     character "X"


              %|X    pad to the end of the line with character "X"



       followup_to
              Type: boolean
              Default: yes

              Controls whether or not the Mail-Followup-To header field is
              generated when sending mail.  When set, Mutt will generate this
              field when you are replying to a known mailing list, specified
              with the "subscribe" or "lists" commands.

              This field has two purposes.  First, preventing you from
              receiving duplicate copies of replies to messages which you send
              to mailing lists.  Second, ensuring that you do get a reply
              separately for any messages sent to known lists to which you are
              not subscribed.  The header will contain only the list's address
              for subscribed lists, and both the list address and your own
              email address for unsubscribed lists.  Without this header, a
              group reply to your message sent to a subscribed list will be
              sent to both the list and your address, resulting in two copies
              of the same email for you.



       force_name
              Type: boolean
              Default: no

              This variable is similar to "$save_name", except that Mutt will
              store a copy of your outgoing message by the username of the
              address you are sending to even if that mailbox does not exist.

              Also see the "$record" variable.



       forward_decode
              Type: boolean
              Default: yes

              Controls the decoding of complex MIME messages into text/plain
              when forwarding a message.  The message header is also RFC2047
              decoded.  This variable is only used, if "$mime_forward" is
              unset, otherwise "$mime_forward_decode" is used instead.



       forward_format
              Type: string
              Default: "[%a: %s]"

              This variable controls the default subject when forwarding a
              message.  It uses the same format sequences as the
              "$index_format" variable.



       forward_quote
              Type: boolean
              Default: no

              When set forwarded messages included in the main body of the
              message (when "$mime_forward" is unset) will be quoted using
              "$indent_string".



       from
              Type: e-mail address
              Default: ""

              When set, this variable contains a default from address.  It can
              be overridden using my_hdr (including from send-hooks) and
              "$reverse_name".

              Defaults to the EMAIL environment variable's content.



       gecos_mask
              Type: regular expression
              Default: "^[^,]*"

              A regular expression used by mutt to parse the GECOS field of a
              password entry when expanding the alias.  By default the regular
              expression is set to "^[^,]*" which will return the string up to
              the first "," encountered.  If the GECOS field contains a string
              like "lastname, firstname" then you should set the
              gecos_mask=".*".

              This can be useful if you see the following behavior: you
              address a e-mail to user ID stevef whose full name is Steve
              Franklin.  If mutt expands stevef to "Franklin" stevef@foo.bar
              then you should set the gecos_mask to a regular expression that
              will match the whole name so mutt will expand "Franklin" to
              "Franklin, Steve".



       hdrs
              Type: boolean
              Default: yes

              When unset, the header fields normally added by the "my_hdr"
              command are not created.  This variable must be unset before
              composing a new message or replying in order to take effect.  If
              set, the user defined header fields are added to every new
              message.



       header
              Type: boolean
              Default: no

              When set, this variable causes Mutt to include the header of the
              message you are replying to into the edit buffer.  The "$weed"
              setting applies.



       help
              Type: boolean
              Default: yes

              When set, help lines describing the bindings for the major
              functions provided by each menu are displayed on the first line
              of the screen.

              Note: The binding will not be displayed correctly if the
              function is bound to a sequence rather than a single keystroke.
              Also, the help line may not be updated if a binding is changed
              while Mutt is running.  Since this variable is primarily aimed
              at new users, neither of these should present a major problem.



       hidden_host
              Type: boolean
              Default: no

              When set, mutt will skip the host name part of "$hostname"
              variable when adding the domain part to addresses.  This
              variable does not affect the generation of Message-IDs, and it
              will not lead to the cut-off of first-level domains.



       hide_limited
              Type: boolean
              Default: no

              When set, mutt will not show the presence of missing messages in
              the thread tree.



       hide_missing
              Type: boolean
              Default: yes

              When set, mutt will not show the presence of messages that are
              hidden by limiting, in the thread tree.



       hide_top_limited
              Type: boolean
              Default: no

              When set, mutt will not show the presence of missing messages at
              the top of threads in the thread tree.  Note that when
              $hide_limited is set, this option will have no effect.



       hide_top_missing
              Type: boolean
              Default: yes

              When set, mutt will not show the presence of messages that are
              hidden by limiting, at the top of threads in the thread
              tree.Note that when $hide_missing is set, this option will have
              no effect.



       history
              Type: number
              Default: 10

              This variable controls the size (in number of strings
              remembered) of the string history buffer. The buffer is cleared
              each time the variable is set.



       honor_followup_to
              Type: quadoption
              Default: yes

              This variable controls whether or not a Mail-Followup-To header
              is honored when group-replying to a message.



       hostname
              Type: string
              Default: ""

              Specifies the hostname to use after the "@" in local e-mail
              addresses.  This overrides the compile time definition obtained
              from /etc/resolv.conf.



       ignore_list_reply_to
              Type: boolean
              Default: no

              Affects the behaviour of the reply function when replying to
              messages from mailing lists.  When set, if the "Reply-To:" field
              is set to the same value as the "To:" field, Mutt assumes that
              the "Reply-To:" field was set by the mailing list to automate
              responses to the list, and will ignore this field.  To direct a
              response to the mailing list when this option is set, use the
              list-reply function; group-reply will reply to both the sender
              and the list.



       imap_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of authentication methods mutt
              may attempt to use to log in to an IMAP server, in the order
              mutt should try them.  Authentication methods are either 'login'
              or the right side of an IMAP 'AUTH=xxx' capability string, eg
              'digest-md5', parameter is unset (the default) mutt will try all
              available methods, in order from most-secure to least-secure.

              Example: set imap_authenticators="gssapi:cram-md5:login"

              Note: Mutt will only fall back to other authentication methods
              if the previous methods are unavailable. If a method is
              available but authentication fails, mutt will not connect to the
              IMAP server.



       imap_delim_chars
              Type: string
              Default: "/."

              This contains the list of characters which you would like to
              treat as folder separators for displaying IMAP paths. In
              particular it helps in using the '=' shortcut for your folder
              variable.



       imap_force_ssl
              Type: boolean
              Default: no

              If this variable is set, Mutt will always use SSL when
              connecting to IMAP servers.



       imap_home_namespace
              Type: string
              Default: ""

              You normally want to see your personal folders alongside your
              INBOX in the IMAP browser. If you see something else, you may
              set this variable to the IMAP path to your folders.



       imap_keepalive
              Type: number
              Default: 900

              This variable specifies the maximum amount of time in seconds
              that mutt will wait before polling open IMAP connections, to
              prevent the server from closing them before mutt has finished
              with them. The default is well within the RFC-specified minimum
              amount of time (30 minutes) before a server is allowed to do
              this, but in practice the RFC does get violated every now and
              then. Reduce this number if you find yourself getting
              disconnected from your IMAP server due to inactivity.



       imap_list_subscribed
              Type: boolean
              Default: no

              This variable configures whether IMAP folder browsing will look
              for only subscribed folders or all folders.  This can be toggled
              in the IMAP browser with the toggle-subscribed function.



       imap_pass
              Type: string
              Default: ""

              Specifies the password for your IMAP account.  If unset, Mutt
              will prompt you for your password when you invoke the fetch-mail
              function.  Warning: you should only use this option when you are
              on a fairly secure machine, because the superuser can read your
              muttrc even if you are the only one who can read the file.



       imap_passive
              Type: boolean
              Default: yes

              When set, mutt will not open new IMAP connections to check for
              new mail.  Mutt will only check for new mail over existing IMAP
              connections.  This is useful if you don't want to be prompted to
              user/password pairs on mutt invocation, or if opening the
              connection is slow.



       imap_peek
              Type: boolean
              Default: yes

              If set, mutt will avoid implicitly marking your mail as read
              whenever you fetch a message from the server. This is generally
              a good thing, but can make closing an IMAP folder somewhat
              slower. This option exists to appease speed freaks.



       imap_servernoise
              Type: boolean
              Default: yes

              When set, mutt will display warning messages from the IMAP
              server as error messages. Since these messages are often
              harmless, or generated due to configuration problems on the
              server which are out of the users' hands, you may wish to
              suppress them at some point.



       imap_user
              Type: string
              Default: ""

              Your login name on the IMAP server.

              This variable defaults to your user name on the local machine.



       implicit_autoview
              Type: boolean
              Default: no

              If set to "yes", mutt will look for a mailcap entry with the
              copiousoutput flag set for every MIME attachment it doesn't have
              an internal viewer defined for.  If such an entry is found, mutt
              will use the viewer defined in that entry to convert the body
              part to text form.



       include
              Type: quadoption
              Default: ask-yes

              Controls whether or not a copy of the message(s) you are
              replying to is included in your reply.



       indent_string
              Type: string
              Default: "> "

              Specifies the string to prepend to each line of text quoted in a
              message to which you are replying.  You are strongly encouraged
              not to change this value, as it tends to agitate the more
              fanatical netizens.



       index_format
              Type: string
              Default: "%4C %Z %{%b %d} %-15.15L (%4l) %s"

              This variable allows you to customize the message index display
              to your personal taste.

              "Format strings" are similar to the strings used in the "C"
              function printf to format output (see the man page for more
              detail).  The following sequences are defined in Mutt:

              %a     address of the author


              %b     filename of the original message folder (think mailBox)


              %B     the list to which the letter was sent, or else the folder
                     name (%b).


              %c     number of characters (bytes) in the message


              %C     current message number


              %d     date and time of the message in the format specified by
                     "date_format" converted to sender's time zone


              %D     date and time of the message in the format specified by
                     "date_format" converted to the local time zone


              %e     current message number in thread


              %E     number of messages in current thread


              %f     entire From: line (address + real name)


              %F     author name, or recipient name if the message is from you


              %i     message-id of the current message


              %l     number of lines in the message


              %L     If an address in the To or CC header field matches an
                     address defined by the users "lists" command, this
                     displays "To <list-name>", otherwise the same as %F.


              %m     total number of message in the mailbox


              %M     number of hidden messages if the thread is collapsed.


              %N     message score


              %n     author's real name (or address if missing)


              %O     (_O_riginal save folder)  Where mutt would formerly have
                     stashed the message: list name or recipient name if no
                     list


              %s     subject of the message


              %S     status of the message (N/D/d/!/r/*)


              %t     `to:' field (recipients)


              %T     the appropriate character from the $to_chars string


              %u     user (login) name of the author


              %v     first name of the author, or the recipient if the message
                     is from you


              %y     `x-label:' field, if present


              %Y     `x-label' field, if present, and (1) not at part of a
                     thread tree, (2) at the top of a thread, or (3) `x-label'
                     is different from preceding message's `x-label'.


              %Z     message status flags


              %{fmt} the date and time of the message is converted to sender's
                     time zone, and "fmt" is expanded by the library function
                     "strftime"; a leading bang disables locales


              %[fmt] the date and time of the message is converted to the
                     local time zone, and "fmt" is expanded by the library
                     function "strftime"; a leading bang disables locales


              %(fmt) the local date and time when the message was received.
                     "fmt" is expanded by the library function "strftime"; a
                     leading bang disables locales


              %<fmt> the current local time. "fmt" is expanded by the library
                     function "strftime"; a leading bang disables locales.


              %>X    right justify the rest of the string and pad with
                     character "X"


              %|X    pad to the end of the line with character "X"


              See also: "$to_chars".



       ispell
              Type: path
              Default: "/usr/local/bin/ispell"

              How to invoke ispell (GNU's spell-checking software).



       keep_flagged
              Type: boolean
              Default: no

              If set, read messages marked as flagged will not be moved from
              your spool mailbox to your "$mbox" mailbox, or as a result of a
              "mbox-hook" command.



       locale
              Type: string
              Default: "C"

              The locale used by strftime(3) to format dates. Legal values are
              the strings your system accepts for the locale variable LC_TIME.



       mail_check
              Type: number
              Default: 5

              This variable configures how often (in seconds) mutt should look
              for new mail.



       mailcap_path
              Type: string
              Default: ""

              This variable specifies which files to consult when attempting
              to display MIME bodies not directly supported by Mutt.



       mailcap_sanitize
              Type: boolean
              Default: yes

              If set, mutt will restrict possible characters in mailcap %
              expandos to a well-defined set of safe characters.  This is the
              safe setting, but we are not sure it doesn't break some more
              advanced MIME stuff.

              DON'T CHANGE THIS SETTING UNLESS YOU ARE REALLY SURE WHAT YOU
              ARE DOING!



       maildir_trash
              Type: boolean
              Default: no

              If set, messages marked as deleted will be saved with the
              maildir (T)rashed flag instead of unlinked.  NOTE: this only
              applies to maildir-style mailboxes.  Setting it will have no
              effect on other mailbox types.



       mark_old
              Type: boolean
              Default: yes

              Controls whether or not Mutt makes the distinction between new
              messages and old unread messages.  By default, Mutt will mark
              new messages as old if you exit a mailbox without reading them.
              The next time you start Mutt, the messages will show up with an
              "O" next to them in the index menu, indicating that they are
              old.  In order to make Mutt treat all unread messages as new
              only, you can unset this variable.



       markers
              Type: boolean
              Default: yes

              Controls the display of wrapped lines in the internal pager. If
              set, a "+" marker is displayed at the beginning of wrapped
              lines. Also see the "$smart_wrap" variable.



       mask
              Type: regular expression
              Default: "!^\.[^.]"

              A regular expression used in the file browser, optionally
              preceded by the not operator "!".  Only files whose names match
              this mask will be shown. The match is always case-sensitive.



       mbox
              Type: path
              Default: "~/mbox"

              This specifies the folder into which read mail in your
              "$spoolfile" folder will be appended.



       mbox_type
              Type: folder magic
              Default: mbox

              The default mailbox type used when creating new folders. May be
              any of mbox, MMDF, MH and Maildir.



       metoo
              Type: boolean
              Default: no

              If unset, Mutt will remove your address (see the "$alternates"
              variable) from the list of recipients when replying to a
              message.



       menu_scroll
              Type: boolean
              Default: no

              When set, menus will be scrolled up or down one line when you
              attempt to move across a screen boundary.  If unset, the screen
              is cleared and the next or previous page of the menu is
              displayed (useful for slow links to avoid many redraws).



       meta_key
              Type: boolean
              Default: no

              If set, forces Mutt to interpret keystrokes with the high bit
              (bit 8) set as if the user had pressed the ESC key and whatever
              key remains after having the high bit removed.  For example, if
              the key pressed has an ASCII value of 0xf4, then this is treated
              as if the user had pressed ESC then "x".  This is because the
              result of removing the high bit from "0xf4" is "0x74", which is
              the ASCII character "x".



       mh_purge
              Type: boolean
              Default: no

              When unset, mutt will mimic mh's behaviour and rename deleted
              messages to ,<old file name> in mh folders instead of really
              deleting them.  If the variable is set, the message files will
              simply be deleted.



       mh_seq_flagged
              Type: string
              Default: "flagged"

              The name of the MH sequence used for flagged messages.



       mh_seq_replied
              Type: string
              Default: "replied"

              The name of the MH sequence used to tag replied messages.



       mh_seq_unseen
              Type: string
              Default: "unseen"

              The name of the MH sequence used for unseen messages.



       mime_forward
              Type: quadoption
              Default: no

              When set, the message you are forwarding will be attached as a
              separate MIME part instead of included in the main body of the
              message.  This is useful for forwarding MIME messages so the
              receiver can properly view the message as it was delivered to
              you. If you like to switch between MIME and not MIME from mail
              to mail, set this variable to ask-no or ask-yes.

              Also see "$forward_decode" and "$mime_forward_decode".



       mime_forward_decode
              Type: boolean
              Default: no

              Controls the decoding of complex MIME messages into text/plain
              when forwarding a message while "$mime_forward" is set.
              Otherwise "$forward_decode" is used instead.



       mime_forward_rest
              Type: quadoption
              Default: yes

              When forwarding multiple attachments of a MIME message from the
              recvattach menu, attachments which cannot be decoded in a
              reasonable manner will be attached to the newly composed message
              if this option is set.



       mix_entry_format
              Type: string
              Default: "%4n %c %-16s %a"

              This variable describes the format of a remailer line on the
              mixmaster chain selection screen.  The following printf-like
              sequences are supported:

              %n     The running number on the menu.


              %c     Remailer capabilities.


              %s     The remailer's short name.


              %a     The remailer's e-mail address.



       mixmaster
              Type: path
              Default: "mixmaster"

              This variable contains the path to the Mixmaster binary on your
              system.  It is used with various sets of parameters to gather
              the list of known remailers, and to finally send a message
              through the mixmaster chain.



       move
              Type: quadoption
              Default: ask-no

              Controls whether you will be asked to confirm moving read
              messages from your spool mailbox to your "$mbox" mailbox, or as
              a result of a "mbox-hook" command.



       message_format
              Type: string
              Default: "%s"

              This is the string displayed in the "attachment" menu for
              attachments of type message/rfc822.  For a full listing of
              defined printf()-like sequences see the section on
              "$index_format".



       pager
              Type: path
              Default: "builtin"

              This variable specifies which pager you would like to use to
              view messages.  builtin means to use the builtin pager,
              otherwise this variable should specify the pathname of the
              external pager you would like to use.

              Using an external pager may have some disadvantages: Additional
              keystrokes are necessary because you can't call mutt functions
              directly from the pager, and screen resizes cause lines longer
              than the screen width to be badly formatted in the help menu.



       pager_context
              Type: number
              Default: 0

              This variable controls the number of lines of context that are
              given when displaying the next or previous page in the internal
              pager.  By default, Mutt will display the line after the last
              one on the screen at the top of the next page (0 lines of
              context).



       pager_format
              Type: string
              Default: "-%Z- %C/%m: %-20.20n   %s"

              This variable controls the format of the one-line message
              "status" displayed before each message in either the internal or
              an external pager.  The valid sequences are listed in the
              "$index_format" section.



       pager_index_lines
              Type: number
              Default: 0

              Determines the number of lines of a mini-index which is shown
              when in the pager.  The current message, unless near the top or
              bottom of the folder, will be roughly one third of the way down
              this mini-index, giving the reader the context of a few messages
              before and after the message.  This is useful, for example, to
              determine how many messages remain to be read in the current
              thread.  One of the lines is reserved for the status bar from
              the index, so a pager_index_lines of 6 will only show 5 lines of
              the actual index.  A value of 0 results in no index being shown.
              If the number of messages in the current folder is less than
              pager_index_lines, then the index will only use as many lines as
              it needs.



       pager_stop
              Type: boolean
              Default: no

              When set, the internal-pager will not move to the next message
              when you are at the end of a message and invoke the next-page
              function.



       pgp_autosign
              Type: boolean
              Default: no

              Setting this variable will cause Mutt to always attempt to
              PGP/MIME sign outgoing messages.  This can be overridden by use
              of the pgp- menu, when signing is not required or encryption is
              requested as well.



       pgp_autoencrypt
              Type: boolean
              Default: no

              Setting this variable will cause Mutt to always attempt to
              PGP/MIME encrypt outgoing messages.  This is probably only
              useful in connection to the send-hook command.  It can be
              overridden by use of the pgp-menu, when encryption is not
              required or signing is requested as well.



       pgp_ignore_subkeys
              Type: boolean
              Default: yes

              Setting this variable will cause Mutt to ignore OpenPGP subkeys.
              Instead, the principal key will inherit the subkeys'
              capabilities.  Unset this if you want to play interesting key
              selection games.



       pgp_entry_format
              Type: string
              Default: "%4n %t%f %4l/0x%k %-4a %2c %u"

              This variable allows you to customize the PGP key selection menu
              to your personal taste. This string is similar to
              "$index_format", but has its own set of printf()-like sequences:

              %n     number


              %k     key id


              %u     user id


              %a     algorithm


              %l     key length


              %f     flags


              %c     capabilities


              %t     trust/validity of the key-uid association


              %[<s>] date of the key where <s> is an strftime(3) expression



       pgp_good_sign
              Type: regular expression
              Default: ""

              If you assign a text to this variable, then a PGP signature is
              only considered verified if the output from $pgp_verify_command
              contains the text. Use this variable if the exit code from the
              command is 0 even for bad signatures.



       pgp_long_ids
              Type: boolean
              Default: no

              If set, use 64 bit PGP key IDs. Unset uses the normal 32 bit Key
              IDs.



       pgp_replyencrypt
              Type: boolean
              Default: yes

              If set, automatically PGP encrypt replies to messages which are
              encrypted.



       pgp_replysign
              Type: boolean
              Default: no

              If set, automatically PGP sign replies to messages which are
              signed.

              Note: this does not work on messages that are encrypted and
              signed!



       pgp_replysignencrypted
              Type: boolean
              Default: no

              If set, automatically PGP sign replies to messages which are
              encrypted. This makes sense in combination with
              "$pgp_replyencrypt", because it allows you to sign all messages
              which are automatically encrypted.  This works around the
              problem noted in "$pgp_replysign", that mutt is not able to find
              out whether an encrypted message is also signed.



       pgp_retainable_sigs
              Type: boolean
              Default: no

              If set, signed and encrypted messages will consist of nested
              multipart/signed and multipart/encrypted body parts.

              This is useful for applications like encrypted and signed
              mailing lists, where the outer layer (multipart/encrypted) can
              be easily removed, while the inner multipart/signed part is
              retained.



       pgp_show_unusable
              Type: boolean
              Default: yes

              If set, mutt will display non-usable keys on the PGP key
              selection menu.  This includes keys which have been revoked,
              have expired, or have been marked as "disabled" by the user.



       pgp_sign_as
              Type: string
              Default: ""

              If you have more than one key pair, this option allows you to
              specify which of your private keys to use.  It is recommended
              that you use the keyid form to specify your key (e.g.,
              "0x00112233").



       pgp_strict_enc
              Type: boolean
              Default: yes

              If set, Mutt will automatically encode PGP/MIME signed messages
              as quoted-printable.  Please note that unsetting this variable
              may lead to problems with non-verifyable PGP signatures, so only
              change this if you know what you are doing.



       pgp_timeout
              Type: number
              Default: 300

              The number of seconds after which a cached passphrase will
              expire if not used.



       pgp_verify_sig
              Type: quadoption
              Default: yes

              If "yes", always attempt to verify PGP/MIME signatures.  If
              "ask-yes" or "ask-no", ask whether or not to verify the
              signature.  If "no", never attempt to verify PGP/MIME
              signatures.



       pgp_sort_keys
              Type: sort order
              Default: address

              Specifies how the entries in the `pgp keys' menu are sorted. The
              following are legal values:

              address
                     sort alphabetically by user id


              keyid  sort alphabetically by key id


              date   sort by key creation date


              trust  sort by the trust of the key


              If you prefer reverse order of the above values, prefix it with
              `reverse-'.



       pgp_create_traditional
              Type: quadoption
              Default: no

              This option controls whether Mutt generates old-style PGP
              encrypted or signed messages under certain circumstances.

              Note that PGP/MIME will be used automatically for messages which
              have a character set different from us-ascii, or which consist
              of more than a single MIME part.

              Also note that using the old-style PGP message format is
              strongly deprecated.



       pgp_decode_command
              Type: string
              Default: ""

              This format strings specifies a command which is used to decode
              application/pgp attachments.

              The PGP command formats have their own set of printf-like
              sequences:

              %p     Expands to PGPPASSFD=0 when a pass phrase is needed, to
                     an empty string otherwise. Note: This may be used with a
                     %? construct.


              %f     Expands to the name of a file containing a message.


              %s     Expands to the name of a file containing the signature
                     part
                                of a multipart/signed attachment when
                     verifying it.


              %a     The value of $pgp_sign_as.


              %r     One or more key IDs.


              For examples on how to configure these formats for the various
              versions of PGP which are floating around, see the pgp*.rc and
              gpg.rc files in the samples/ subdirectory which has been
              installed on your system alongside the documentation.



       pgp_getkeys_command
              Type: string
              Default: ""

              This command is invoked whenever mutt will need public key
              information.  %r is the only printf-like sequence used with this
              format.



       pgp_verify_command
              Type: string
              Default: ""

              This command is used to verify PGP/MIME signatures.



       pgp_decrypt_command
              Type: string
              Default: ""

              This command is used to decrypt a PGP/MIME encrypted message.



       pgp_clearsign_command
              Type: string
              Default: ""

              This format is used to create a "clearsigned" old-style PGP
              attachment.  Note that the use of this format is strongly
              deprecated.



       pgp_sign_command
              Type: string
              Default: ""

              This command is used to create the detached PGP signature for a
              multipart/signed PGP/MIME body part.



       pgp_encrypt_sign_command
              Type: string
              Default: ""

              This command is used to combinedly sign/encrypt a body part.



       pgp_encrypt_only_command
              Type: string
              Default: ""

              This command is used to encrypt a body part without signing it.



       pgp_import_command
              Type: string
              Default: ""

              This command is used to import a key from a message into the
              user's public key ring.



       pgp_export_command
              Type: string
              Default: ""

              This command is used to export a public key from the user's key
              ring.



       pgp_verify_key_command
              Type: string
              Default: ""

              This command is used to verify key information from the key
              selection menu.



       pgp_list_secring_command
              Type: string
              Default: ""

              This command is used to list the secret key ring's contents.
              The output format must be analogous to the one used by gpg
              --list-keys --with-colons.

              This format is also generated by the pgpring utility which comes
              with mutt.



       pgp_list_pubring_command
              Type: string
              Default: ""

              This command is used to list the public key ring's contents.
              The output format must be analogous to the one used by gpg
              --list-keys --with-colons.

              This format is also generated by the pgpring utility which comes
              with mutt.



       forward_decrypt
              Type: boolean
              Default: yes

              Controls the handling of encrypted messages when forwarding a
              message.  When set, the outer layer of encryption is stripped
              off.  This variable is only used if "$mime_forward" is set and
              "$mime_forward_decode" is unset.



       ssl_starttls
              Type: quadoption
              Default: yes

              If set (the default), mutt will attempt to use STARTTLS on
              servers advertising the capability. When unset, mutt will not
              attempt to use STARTTLS regardless of the server's capabilities.



       certificate_file
              Type: path
              Default: ""

              This variable specifies the file where the certificates you
              trust are saved. When an unknown certificate is encountered, you
              are asked if you accept it or not. If you accept it, the
              certificate can also be saved in this file and further
              connections are automatically accepted.

              You can also manually add CA certificates in this file. Any
              server certificate that is signed with one of these CA
              certificates are also automatically accepted.

              Example: set certificate_file=~/.mutt/certificates



       ssl_usesystemcerts
              Type: boolean
              Default: yes

              If set to yes, mutt will use CA certificates in the system-wide
              certificate store when checking if server certificate is signed
              by a trusted CA.



       entropy_file
              Type: path
              Default: ""

              The file which includes random data that is used to initalize
              SSL library functions.



       ssl_use_sslv2
              Type: boolean
              Default: yes

              This variables specifies whether to attempt to use SSLv2 in the
              SSL authentication process.



       ssl_use_sslv3
              Type: boolean
              Default: yes

              This variables specifies whether to attempt to use SSLv3 in the
              SSL authentication process.



       ssl_use_tlsv1
              Type: boolean
              Default: yes

              This variables specifies whether to attempt to use TLSv1 in the
              SSL authentication process.



       pipe_split
              Type: boolean
              Default: no

              Used in connection with the pipe-message command and the "tag-
              prefix" operator.  If this variable is unset, when piping a list
              of tagged messages Mutt will concatenate the messages and will
              pipe them as a single folder.  When set, Mutt will pipe the
              messages one by one.  In both cases the messages are piped in
              the current sorted order, and the "$pipe_sep" separator is added
              after each message.



       pipe_decode
              Type: boolean
              Default: no

              Used in connection with the pipe-message command.  When unset,
              Mutt will pipe the messages without any preprocessing. When set,
              Mutt will weed headers and will attempt to PGP/MIME decode the
              messages first.



       pipe_sep
              Type: string
              Default: "\n"

              The separator to add between messages when piping a list of
              tagged messages to an external Unix command.



       pop_authenticators
              Type: string
              Default: ""

              This is a colon-delimited list of authentication methods mutt
              may attempt to use to log in to an POP server, in the order mutt
              should try them.  Authentication methods are either 'user',
              'apop' or any SASL mechanism, eg 'digest-md5', 'gssapi' or
              'cram-md5'.  This parameter is case-insensitive. If this
              parameter is unset (the default) mutt will try all available
              methods, in order from most-secure to least-secure.

              Example: set pop_authenticators="digest-md5:apop:user"



       pop_auth_try_all
              Type: boolean
              Default: yes

              If set, Mutt will try all available methods. When unset, Mutt
              will only fall back to other authentication methods if the
              previous methods are unavailable. If a method is available but
              authentication fails, Mutt will not connect to the POP server.



       pop_checkinterval
              Type: number
              Default: 60

              This variable configures how often (in seconds) POP should look
              for new mail.



       pop_delete
              Type: quadoption
              Default: ask-no

              If set, Mutt will delete successfully downloaded messages from
              the POP server when using the fetch-mail function.  When unset,
              Mutt will download messages but also leave them on the POP
              server.



       pop_host
              Type: string
              Default: ""

              The name of your POP server for the fetch-mail function.  You
              can also specify an alternative port, username and password, ie:

              [pop[s]://][username[:password]@]popserver[:port]



       pop_last
              Type: boolean
              Default: no

              If this variable is set, mutt will try to use the "LAST" POP
              command for retrieving only unread messages from the POP server
              when using the fetch-mail function.



       pop_reconnect
              Type: quadoption
              Default: ask-yes

              Controls whether or not Mutt will try to reconnect to POP server
              when connection lost.



       pop_user
              Type: string
              Default: ""

              Your login name on the POP server.

              This variable defaults to your user name on the local machine.



       pop_pass
              Type: string
              Default: ""

              Specifies the password for your POP account.  If unset, Mutt
              will prompt you for your password when you open POP mailbox.
              Warning: you should only use this option when you are on a
              fairly secure machine, because the superuser can read your
              muttrc even if you are the only one who can read the file.



       post_indent_string
              Type: string
              Default: ""

              Similar to the "$attribution" variable, Mutt will append this
              string after the inclusion of a message which is being replied
              to.



       postpone
              Type: quadoption
              Default: ask-yes

              Controls whether or not messages are saved in the "$postponed"
              mailbox when you elect not to send immediately.



       postponed
              Type: path
              Default: "~/postponed"

              Mutt allows you to indefinitely "postpone sending a message"
              which you are editing.  When you choose to postpone a message,
              Mutt saves it in the mailbox specified by this variable.  Also
              see the "$postpone" variable.



       preconnect
              Type: string
              Default: ""

              If set, a shell command to be executed if mutt fails to
              establish a connection to the server. This is useful for setting
              up secure connections, e.g. with ssh(1). If the command returns
              a  nonzero status, mutt gives up opening the server. Example:

              preconnect="ssh -f -q -L 1234:mailhost.net:143 mailhost.net
              sleep 20 < /dev/null > /dev/null"

              Mailbox 'foo' on mailhost.net can now be reached as
              '{localhost:1234}foo'.

              NOTE: For this example to work, you must be able to log in to
              the remote machine without having to enter a password.



       print
              Type: quadoption
              Default: ask-no

              Controls whether or not Mutt asks for confirmation before
              printing.  This is useful for people (like me) who accidentally
              hit "p" often.



       print_command
              Type: path
              Default: "lpr"

              This specifies the command pipe that should be used to print
              messages.



       print_decode
              Type: boolean
              Default: yes

              Used in connection with the print-message command.  If this
              option is set, the message is decoded before it is passed to the
              external command specified by $print_command.  If this option is
              unset, no processing will be applied to the message when
              printing it.  The latter setting may be useful if you are using
              some advanced printer filter which is able to properly format e-
              mail messages for printing.



       print_split
              Type: boolean
              Default: no

              Used in connection with the print-message command.  If this
              option is set, the command sepcified by $print_command is
              executed once for each message which is to be printed.  If this
              option is unset, the command specified by $print_command is
              executed only once, and all the messages are concatenated, with
              a form feed as the message separator.

              Those who use the enscript(1) program's mail-printing mode will
              most likely want to set this option.



       prompt_after
              Type: boolean
              Default: yes

              If you use an external "$pager", setting this variable will
              cause Mutt to prompt you for a command when the pager exits
              rather than returning to the index menu.  If unset, Mutt will
              return to the index menu when the external pager exits.



       query_command
              Type: path
              Default: ""

              This specifies the command that mutt will use to make external
              address queries.  The string should contain a %s, which will be
              substituted with the query string the user types.  See "query"
              for more information.



       quit
              Type: quadoption
              Default: yes

              This variable controls whether "quit" and "exit" actually quit
              from mutt.  If it set to yes, they do quit, if it is set to no,
              they have no effect, and if it is set to ask-yes or ask-no, you
              are prompted for confirmation when you try to quit.



       quote_regexp
              Type: regular expression
              Default: "^([ \t]*[|>:}#])+"

              A regular expression used in the internal-pager to determine
              quoted sections of text in the body of a message.

              Note: In order to use the quotedx patterns in the internal
              pager, you need to set this to a regular expression that matches
              exactly the quote characters at the beginning of quoted lines.



       read_inc
              Type: number
              Default: 10

              If set to a value greater than 0, Mutt will display which
              message it is currently on when reading a mailbox.  The message
              is printed after read_inc messages have been read (e.g., if set
              to 25, Mutt will print a message when it reads message 25, and
              then again when it gets to message 50).  This variable is meant
              to indicate progress when reading large mailboxes which may take
              some time.  When set to 0, only a single message will appear
              before the reading the mailbox.

              Also see the "$write_inc" variable.



       read_only
              Type: boolean
              Default: no

              If set, all folders are opened in read-only mode.



       realname
              Type: string
              Default: ""

              This variable specifies what "real" or "personal" name should be
              used when sending messages.

              By default, this is the GCOS field from /etc/passwd.  Note that
              this variable will not be used when the user has set a real name
              in the $from variable.



       recall
              Type: quadoption
              Default: ask-yes

              Controls whether or not you are prompted to recall postponed
              messages when composing a new message.  Also see "$postponed".

              Setting this variable to "yes" is not generally useful, and thus
              not recommended.



       record
              Type: path
              Default: ""

              This specifies the file into which your outgoing messages should
              be appended.  (This is meant as the primary method for saving a
              copy of your messages, but another way to do this is using the
              "my_hdr" command to create a Bcc: field with your email address
              in it.)

              The value of $record is overridden by the "$force_name" and
              "$save_name" variables, and the "fcc-hook" command.



       reply_regexp
              Type: regular expression
              Default: "^(re([\[0-9\]+])*|aw):[ \t]*"

              A regular expression used to recognize reply messages when
              threading and replying. The default value corresponds to the
              English "Re:" and the German "Aw:".



       reply_self
              Type: boolean
              Default: no

              If unset and you are replying to a message sent by you, Mutt
              will assume that you want to reply to the recipients of that
              message rather than to yourself.



       reply_to
              Type: quadoption
              Default: ask-yes

              If set, Mutt will ask you if you want to use the address listed
              in the Reply-To: header field when replying to a message.  If
              you answer no, it will use the address in the From: header field
              instead.  This option is useful for reading a mailing list that
              sets the Reply-To: header field to the list address and you want
              to send a private message to the author of a message.



       resolve
              Type: boolean
              Default: yes

              When set, the cursor will be automatically advanced to the next
              (possibly undeleted) message whenever a command that modifies
              the current message is executed.



       reverse_alias
              Type: boolean
              Default: no

              This variable controls whether or not Mutt will display the
              "personal" name from your aliases in the index menu if it finds
              an alias that matches the message's sender.  For example, if you
              have the following alias:

              alias juser abd30425@somewhere.net (Joe User)



              and then you receive mail which contains the following header:

              From: abd30425@somewhere.net



              It would be displayed in the index menu as "Joe User" instead of
              "abd30425@somewhere.net."  This is useful when the person's e-
              mail address is not human friendly (like CompuServe addresses).



       reverse_name
              Type: boolean
              Default: no

              It may sometimes arrive that you receive mail to a certain
              machine, move the messages to another machine, and reply to some
              the messages from there.  If this variable is set, the default
              From: line of the reply messages is built using the address
              where you received the messages you are replying to.  If the
              variable is unset, the From: line will use your address on the
              current machine.



       reverse_realname
              Type: boolean
              Default: yes

              This variable fine-tunes the behaviour of the reverse_name
              feature.  When it is set, mutt will use the address from
              incoming messages as-is, possibly including eventual real names.
              When it is unset, mutt will override any such realnames with the
              setting of the realname variable.



       rfc2047_parameters
              Type: boolean
              Default: no

              When this variable is set, Mutt will decode RFC-2047-encoded
              MIME parameters. You want to set this variable when mutt
              suggests you to save attachments to files named like this:
              =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=

              When this variable is set interactively, the change doesn't have
              the desired effect before you have changed folders.

              Note that this use of RFC 2047's encoding is explicitly,
              prohibited by the standard, but nevertheless encountered in the
              wild.  Also note that setting this parameter will not have the
              effect that mutt generates this kind of encoding.  Instead, mutt
              will unconditionally use the encoding specified in RFC 2231.



       save_address
              Type: boolean
              Default: no

              If set, mutt will take the sender's full address when choosing a
              default folder for saving a mail. If "$save_name" or
              "$force_name" is set too, the selection of the fcc folder will
              be changed as well.



       save_empty
              Type: boolean
              Default: yes

              When unset, mailboxes which contain no saved messages will be
              removed when closed (the exception is "$spoolfile" which is
              never removed).  If set, mailboxes are never removed.

              Note: This only applies to mbox and MMDF folders, Mutt does not
              delete MH and Maildir directories.



       save_name
              Type: boolean
              Default: no

              This variable controls how copies of outgoing messages are
              saved.  When set, a check is made to see if a mailbox specified
              by the recipient address exists (this is done by searching for a
              mailbox in the "$folder" directory with the username part of the
              recipient address).  If the mailbox exists, the outgoing message
              will be saved to that mailbox, otherwise the message is saved to
              the "$record" mailbox.

              Also see the "$force_name" variable.



       score
              Type: boolean
              Default: yes

              When this variable is unset, scoring is turned off.  This can be
              useful to selectively disable scoring for certain folders when
              the "$score_threshold_delete" variable and friends are used.



       score_threshold_delete
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than
              the value of this variable are automatically marked for deletion
              by mutt.  Since mutt scores are always greater than or equal to
              zero, the default setting of this variable will never mark a
              message for deletion.



       score_threshold_flag
              Type: number
              Default: 9999

              Messages wich have been assigned a score greater than or equal
              to this variable's value are automatically marked "flagged".



       score_threshold_read
              Type: number
              Default: -1

              Messages which have been assigned a score equal to or lower than
              the value of this variable are automatically marked as read by
              mutt.  Since mutt scores are always greater than or equal to
              zero, the default setting of this variable will never mark a
              message read.



       send_charset
              Type: string
              Default: "us-ascii:iso-8859-1:utf-8"

              A list of character sets for outgoing messages. Mutt will use
              the first character set into which the text can be converted
              exactly.  If your "$charset" is not iso-8859-1 and recipients
              may not understand UTF-8, it is advisable to include in the list
              an appropriate widely used standard character set (such as
              iso-8859-2, koi8-r or iso-2022-jp) either instead of or after
              "iso-8859-1".



       sendmail
              Type: path
              Default: "/usr/sbin/sendmail -oem -oi"

              Specifies the program and arguments used to deliver mail sent by
              Mutt.  Mutt expects that the specified program interprets
              additional arguments as recipient addresses.



       sendmail_wait
              Type: number
              Default: 0

              Specifies the number of seconds to wait for the "$sendmail"
              process to finish before giving up and putting delivery in the
              background.

              Mutt interprets the value of this variable as follows:


              >0     number of seconds to wait for sendmail to finish before
                     continuing


              0      wait forever for sendmail to finish


              <0     always put sendmail in the background without waiting


              Note that if you specify a value other than 0, the output of the
              child process will be put in a temporary file.  If there is some
              error, you will be informed as to where to find the output.



       shell
              Type: path
              Default: ""

              Command to use when spawning a subshell.  By default, the user's
              login shell from /etc/passwd is used.



       sig_dashes
              Type: boolean
              Default: yes

              If set, a line containing "-- " will be inserted before your
              "$signature".  It is strongly recommended that you not unset
              this variable unless your "signature" contains just your name.
              The reason for this is because many software packages use "--
              \n" to detect your signature.  For example, Mutt has the ability
              to highlight the signature in a different color in the builtin
              pager.



       sig_on_top
              Type: boolean
              Default: no

              If set, the signature will be included before any quoted or
              forwarded text.  It is strongly recommended that you do not set
              this variable unless you really know what you are doing, and are
              prepared to take some heat from netiquette guardians.



       signature
              Type: path
              Default: "~/.signature"

              Specifies the filename of your signature, which is appended to
              all outgoing messages.   If the filename ends with a pipe ("|"),
              it is assumed that filename is a shell command and input should
              be read from its stdout.



       simple_search
              Type: string
              Default: "~f %s | ~s %s"

              Specifies how Mutt should expand a simple search into a real
              search pattern.  A simple search is one that does not contain
              any of the ~ operators.  See "patterns" for more information on
              search patterns.

              For example, if you simply type joe at a search or limit prompt,
              Mutt will automatically expand it to the value specified by this
              variable.  For the default value it would be:

              ~f joe | ~s joe



       smart_wrap
              Type: boolean
              Default: yes

              Controls the display of lines longer then the screen width in
              the internal pager. If set, long lines are wrapped at a word
              boundary.  If unset, lines are simply wrapped at the screen
              edge. Also see the "$markers" variable.



       smileys
              Type: regular expression
              Default: "(>From )|(:[-^]?[][)(><}{|/DP])"

              The pager uses this variable to catch some common false
              positives of "$quote_regexp", most notably smileys in the
              beginning of a line



       sleep_time
              Type: number
              Default: 1

              Specifies time, in seconds, to pause while displaying certain
              informational messages, while moving from folder to folder and
              after expunging messages from the current folder.  The default
              is to pause one second, so a value of zero for this option
              suppresses the pause.



       sort
              Type: sort order
              Default: date

              Specifies how to sort messages in the index menu.  Valid values
              are:

                 date or date-sent
                 date-received
                 from
                 mailbox-order (unsorted)
                 score
                 size
                 subject
                 threads
                 to



              You may optionally use the reverse- prefix to specify reverse
              sorting order (example: set sort=reverse-date-sent).



       sort_alias
              Type: sort order
              Default: alias

              Specifies how the entries in the `alias' menu are sorted.  The
              following are legal values:

                 address (sort alphabetically by email address)
                 alias (sort alphabetically by alias name)
                 unsorted (leave in order specified in .muttrc)





       sort_aux
              Type: sort order
              Default: date

              When sorting by threads, this variable controls how threads are
              sorted in relation to other threads, and how the branches of the
              thread trees are sorted.  This can be set to any value that
              "$sort" can, except threads (in that case, mutt will just use
              date-sent).  You can also specify the last- prefix in addition
              to the reverse- prefix, but last- must come after reverse-.  The
              last- prefix causes messages to be sorted against its siblings
              by which has the last descendant, using the rest of sort_aux as
              an ordering.  For instance, set sort_aux=last- date-received
              would mean that if a new message is received in a thread, that
              thread becomes the last one displayed (or the first, if you have
              set sort=reverse-threads.) Note: For reversed "$sort" order
              $sort_aux is reversed again (which is not the right thing to do,
              but kept to not break any existing configuration setting).



       sort_browser
              Type: sort order
              Default: subject

              Specifies how to sort entries in the file browser.  By default,
              the entries are sorted alphabetically.  Valid values:

                 alpha (alphabetically)
                 date
                 size
                 unsorted



              You may optionally use the reverse- prefix to specify reverse
              sorting order (example: set sort_browser=reverse-date).



       sort_re
              Type: boolean
              Default: yes

              This variable is only useful when sorting by threads with
              "$strict_threads" unset.  In that case, it changes the heuristic
              mutt uses to thread messages by subject.  With sort_re set, mutt
              will only attach a message as the child of another message by
              subject if the subject of the child message starts with a
              substring matching the setting of "$reply_regexp".  With sort_re
              unset, mutt will attach the message whether or not this is the
              case, as long as the non-"$reply_regexp" parts of both messages
              are identical.



       spoolfile
              Type: path
              Default: ""

              If your spool mailbox is in a non-default place where Mutt
              cannot find it, you can specify its location with this variable.
              Mutt will automatically set this variable to the value of the
              environment variable $MAIL if it is not set.



       status_chars
              Type: string
              Default: "-*%A"

              Controls the characters used by the "%r" indicator in
              "$status_format". The first character is used when the mailbox
              is unchanged. The second is used when the mailbox has been
              changed, and it needs to be resynchronized. The third is used if
              the mailbox is in read-only mode, or if the mailbox will not be
              written when exiting that mailbox (You can toggle whether to
              write changes to a mailbox with the toggle-write operation,
              bound by default to "%"). The fourth is used to indicate that
              the current folder has been opened in attach- message mode
              (Certain operations like composing a new mail, replying,
              forwarding, etc. are not permitted in this mode).



       status_format
              Type: string
              Default: "-%r-Mutt: %f [Msgs:%?M?%M/?%m%?n? New:%n?%?o? Old:%o?%?d? Del:%d?%?F? Flag:%F?%?t? Tag:%t?%?p? Post:%p?%?b? Inc:%b?%?l? %l?]---(%s/%S)-%>-(%P)---"

              Controls the format of the status line displayed in the index
              menu.  This string is similar to "$index_format", but has its
              own set of printf()-like sequences:

              %b     number of mailboxes with new mail *


              %d     number of deleted messages *


              %h     local hostname


              %f     the full pathname of the current mailbox


              %F     number of flagged messages *


              %l     size (in bytes) of the current mailbox *


              %L     size (in bytes) of the messages shown (i.e., which match
                     the current limit) *


              %m     the number of messages in the mailbox *


              %M     the number of messages shown (i.e., which match the
                     current limit) *


              %n     number of new messages in the mailbox *


              %o     number of old unread messages


              %p     number of postponed messages *


              %P     percentage of the way through the index


              %r     modified/read-only/won't-write/attach-message indicator,
                     according to $status_chars


              %s     current sorting mode ($sort)


              %S     current aux sorting method ($sort_aux)


              %t     number of tagged messages *


              %u     number of unread messages *


              %v     Mutt version string


              %V     currently active limit pattern, if any *


              %>X    right justify the rest of the string and pad with "X"


              %|X    pad to the end of the line with "X"


              * = can be optionally printed if nonzero

              Some of the above sequences can be used to optionally print a
              string if their value is nonzero.  For example, you may only
              want to see the number of flagged messages if such messages
              exist, since zero is not particularly meaningful.  To optionally
              print a string based upon one of the above sequences, the
              following construct is used

              %?<sequence_char>?<optional_string>?

              where sequence_char is a character from the table above, and
              optional_string is the string you would like printed if
              status_char is nonzero.  optional_string may contain other
              sequence as well as normal text, but you may not nest optional
              strings.

              Here is an example illustrating how to optionally print the
              number of new messages in a mailbox: %?n?%n new messages.?

              Additionally you can switch between two strings, the first one,
              if a value is zero, the second one, if the value is nonzero, by
              using the following construct:
              %?<sequence_char>?<if_string>&<else_string>?

              You can additionally force the result of any printf-like
              sequence to be lowercase by prefixing the sequence character
              with an underscore (_) sign.  For example, if you want to
              display the local hostname in lowercase, you would use: %_h



       status_on_top
              Type: boolean
              Default: no

              Setting this variable causes the "status bar" to be displayed on
              the first line of the screen rather than near the bottom.



       strict_threads
              Type: boolean
              Default: no

              If set, threading will only make use of the "In-Reply-To" and
              "References" fields when you "$sort" by message threads.  By
              default, messages with the same subject are grouped together in
              "pseudo threads."  This may not always be desirable, such as in
              a personal mailbox where you might have several unrelated
              messages with the subject "hi" which will get grouped together.



       suspend
              Type: boolean
              Default: yes

              When unset, mutt won't stop when the user presses the terminal's
              susp key, usually "control-Z". This is useful if you run mutt
              inside an xterm using a command like xterm -e mutt.



       text_flowed
              Type: boolean
              Default: no

              When set, mutt will generate text/plain; format=flowed
              attachments.  This format is easier to handle for some mailing
              software, and generally just looks like ordinary text.  To
              actually make use of this format's features, you'll need support
              in your editor.

              Note that $indent_string is ignored when this option is set.



       thread_received
              Type: boolean
              Default: no

              When set, mutt uses the date received rather than the date sent
              to thread messages by subject.



       thorough_search
              Type: boolean
              Default: no

              Affects the ~b and ~h search operations described in section
              "patterns" above.  If set, the headers and attachments of
              messages to be searched are decoded before searching.  If unset,
              messages are searched as they appear in the folder.



       tilde
              Type: boolean
              Default: no

              When set, the internal-pager will pad blank lines to the bottom
              of the screen with a tilde (~).



       timeout
              Type: number
              Default: 600

              This variable controls the number of seconds Mutt will wait for
              a key to be pressed in the main menu before timing out and
              checking for new mail.  A value of zero or less will cause Mutt
              not to ever time out.



       tmpdir
              Type: path
              Default: ""

              This variable allows you to specify where Mutt will place its
              temporary files needed for displaying and composing messages.



       to_chars
              Type: string
              Default: " +TCFL"

              Controls the character used to indicate mail addressed to you.
              The first character is the one used when the mail is NOT
              addressed to your address (default: space).  The second is used
              when you are the only recipient of the message (default: +).
              The third is when your address appears in the TO header field,
              but you are not the only recipient of the message (default: T).
              The fourth character is used when your address is specified in
              the CC header field, but you are not the only recipient.  The
              fifth character is used to indicate mail that was sent by you.
              The sixth character is used to indicate when a mail was sent to
              a mailing-list you subscribe to (default: L).



       tunnel
              Type: string
              Default: ""

              Setting this variable will cause mutt to open a pipe to a
              command instead of a raw socket. You may be able to use this to
              set up preauthenticated connections to your IMAP/POP3 server.
              Example:

              tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"

              NOTE: For this example to work you must be able to log in to the
              remote machine without having to enter a password.



       use_8bitmime
              Type: boolean
              Default: no

              Warning: do not set this variable unless you are using a version
              of sendmail which supports the -B8BITMIME flag (such as sendmail
              8.8.x) or you may not be able to send mail.

              When set, Mutt will invoke "$sendmail" with the -B8BITMIME flag
              when sending 8-bit messages to enable ESMTP negotiation.



       use_domain
              Type: boolean
              Default: yes

              When set, Mutt will qualify all local addresses (ones without
              the @host portion) with the value of "$hostname".  If unset, no
              addresses will be qualified.



       use_from
              Type: boolean
              Default: yes

              When set, Mutt will generate the `From:' header field when
              sending messages.  If unset, no `From:' header field will be
              generated unless the user explicitly sets one using the "my_hdr"
              command.



       use_ipv6
              Type: boolean
              Default: yes

              When set, Mutt will look for IPv6 addresses of hosts it tries to
              contact.  If this option is unset, Mutt will restrict itself to
              IPv4 addresses.  Normally, the default should work.



       user_agent
              Type: boolean
              Default: yes

              When set, mutt will add a "User-Agent" header to outgoing
              messages, indicating which version of mutt was used for
              composing them.



       visual
              Type: path
              Default: ""

              Specifies the visual editor to invoke when the ~v command is
              given in the builtin editor.



       wait_key
              Type: boolean
              Default: yes

              Controls whether Mutt will ask you to press a key after shell-
              escape, pipe-message, pipe-entry, print-message, and print-entry
              commands.

              It is also used when viewing attachments with "auto_view",
              provided that the corresponding mailcap entry has a
              needsterminal flag, and the external program is interactive.

              When set, Mutt will always ask for a key. When unset, Mutt will
              wait for a key only if the external command returned a non-zero
              status.



       weed
              Type: boolean
              Default: yes

              When set, mutt will weed headers when when displaying,
              forwarding, printing, or replying to messages.



       wrap_search
              Type: boolean
              Default: yes

              Controls whether searches wrap around the end of the mailbox.

              When set, searches will wrap around the first (or last) message.
              When unset, searches will not wrap.



       wrapmargin
              Type: number
              Default: 0

              Controls the margin left at the right side of the terminal when
              mutt's pager does smart wrapping.



       write_inc
              Type: number
              Default: 10

              When writing a mailbox, a message will be printed every
              write_inc messages to indicate progress.  If set to 0, only a
              single message will be displayed before writing a mailbox.

              Also see the "$read_inc" variable.



       write_bcc
              Type: boolean
              Default: yes

              Controls whether mutt writes out the Bcc header when preparing
              messages to be sent.  Exim users may wish to use this.
