NAME
       mailbot - A MIME-aware autoresponder utility

SYNOPSIS
       mailbot [options] {program} [arg...]

       In .mailfilter:

       if (/^Subject: *info/)
       {
            cc "| mailbot -t /usr/share/autoresponse/info -d autoresponsedb \
                   -A 'From: info@domain.com' /usr/bin/sendmail -f ''"
       }

DESCRIPTION
       mailbot reads an E-mail message on standard input and creates an E-mail
       message replying to the original message's sender. A program is
       specified as an argument to mailbot after all of mailbot options.
       program is expected to read the created autoreply on its standard
       input, and mail it. If program is not specified, mailbot runs 'sendmail
       -f ""'.

       mailbot has several options for suppressing duplicate autoresponse
       messages. If mailbot chooses not to send an autoresponse, it quietly
       terminates without running program. The autoresponse is optionally
       formatted as a MIME delivery status notification.

       The text of the autoresponse is specified by the -t or the -m argument.
       Either one is required. Everything else is optional. The default
       behavior is to send an autoresponse unless the original message has the
       "Precedence: junk" or the "Precedence: bulk" header, or the
       "Precedence: list" header, or the "List-ID:" header, or if its MIME
       content type is "multipart/report" (this is the MIME content type for
       delivery status notifications). The -M option formats the the
       autoresponse itself as a MIME delivery status notification.

OPTIONS
       -A "header: value"
           Add a header to the autoresponse. Multiple -A options are allowed.
           In most situations, the -A option must be used to set the "From:"
           header in the autogenerated response.

       -faddress
           Address the autoresponse to address, which must be an RFC 2822[1]
           address. By default mailbot takes the autoresponse address from the
           From: (or the Reply-To:) header in the original message.  -f, if
           present, overrides and explicitly sets the autoresponse address.
           "address" must immediately follow the -f option without an
           intervening space (it's a single command line argument). An -f
           option without an address takes the address from the SENDER
           environment variable.

       -t filename
           Read text autoresponse from filename, which must contain a plain
           text message in "flowed-text" format. In a "flowed-text"-formatted
           message, each line that ends with a space character indicates that
           the line logically flows into the next line. This allows the
           message to be reformatted for any shown display width.

               Note
               Messages in languages (see the -c option) which use spaces as
               word delimiters must have two spaces at the end of a flowed
               line. The last space on a flowed line is logically removed, and
               the first space separates the last word on the previous line
               from the first word on the next line. Otherwise, the two words
               will not have a logical space between them if they get
               repositioned as part of adjusting the message's width for
               display.

               Messages in ideographic languages that do not use spaces as
               word delimiters need only one space trailing a flowed line.

               Note
               The trailing whitespace has no visual impact when shown by
               software that does not implemented flowed text format, and
               always displays messages using their original width.

       -c charset
           Set the autoresponse's MIME character set to charset. Run mailbot
           without any arguments to see the default character set.

       -m filename
           Read a MIME autoresponse from filename. This is similar to the -t
           option, except that filename contains MIME headers, followed by a
           blank line, and the corresponding MIME content. The contents of
           filename are inserted in the autoresponse without further
           processing.

           The specified file must contain the "Content-Type" header
           specifying the "text/plain" MIME type, with the "format=flowed",
           "delsp=yes", and the "charset" attributes, which override the -c
           parameter. If the specified file has a "Content-Transfer-Encoding"
           header it must be either "7bit" or "8bit", it may not be
           "quoted-printable".  mailbot always drops any existing
           "Content-Transfer-Encoding" header and always adds the
           "Content-Transfer-Encoding: 8bit" header, even with the -m, since
           the salutation inserted into the message includes the sender's
           name, which may contain 8-bit characters. Example:

               Content-Type: text/plain; format=flowed; delsp=yes; charset="iso-8859-1"

               Mary had a little lamb,
               Its fleece was white as snow.
               And everywhere Mary went,
               The lamb was sure to go.

               Note
               When the -m option is specified mailbot ignores the locale's
               character set and formats the autoreply according to the
               character set read from the "Content-Type" header.

       -M address
           Format the autoresponse as a delivery status notification (RFC
           1894[2]).  address is an RFC 2822[1] E-mail address that generates
           the DSN. Note that the -A option should still be used in addition
           to -M in order to set the From: header on the autoresponse.  -M
           sets the DSN address only. The -M option automatically sets -T
           replydsn

       -T format
           Set the reply format.  format must be one of the following values:

           o    "reply" - the default reply format.

           o    "replyall" - like "reply", except also puts the recipients in
               the original message's "To:" and "Cc:" headers into the "Cc:"
               header of the generated reply.

           o    "replydsn" - like "reply", except the message is formatted as
               a delivery status notification.

           o    "forward" - attach the original message as forwarded text.

           o    "forwardatt" - attach the original message as a forwarded
               message attachment.

       -N
           Do not quote the contents of the original message in the message
           create by "reply", "replyall", and "replydsn" options.

               Note
               The original message gets quoted, in the absence of this
               option, only if the original message was formatted as plain
               text.  mailbot is unable to quote an original message which was
               formatted as HTML, or any other non-plaintext format.

       -e
           Generate a reply ("reply"-formats) to the address listed in any
           "Errors-To" or "Return-Path" header, if present, instead of the
           "From" header.

       -S "salutation"
           Use the given salutation in the "reply". The default value is "%F
           writes:". The following substitutions are recognized in the
           salutation string:

           o    %% - an explicit % character.

           o    %n - a newline character.

           o    %C - the "X-Newsgroup:" header from the original message.

           o    %N - the "Newsgroups:" header from the original message.

           o    %i - the "Message-ID:" header from the original message.

           o    %f - the original message's sender's address.

           o    %F - the original message's sender's name.

           o    %S - the "Subject:" header from the original message

           o    %d - the original message's date, in the local timezone.

           o    %{...}d - use strftime() to format the original message's
               date. A plain %d is equivalent to %{%a, %d %b %Y %H:%M:%S %z}d.
               All other characters in the salutation string are left as is.

           -F "marker"
               When generating a forward, use the marker to separate the
               forwarded message from the autoreply text, instead of the
               default "--- Forwarded message ---"

           -r addrlist

               addrlist is a comma-separated list of RFC 2822[1] E-mail
               addresses.  mailbot sends an autoresponse only if the original
               message has at least one of the specified addresses in any To:
               or Cc: header.

           -d filename
               Create a small database, filename, that keeps track of sender's
               E-mail addresses, and prevent duplicate autoresponses going to
               the same address (suppress autoresponses going back to the same
               senders, for subsequent received messages). The -d option is
               only available if maildrop has GDBM/DB extensions enabled.

           -D x
               Do not send duplicate autoresponses (see the -d option) for at
               least x days (default: 1 day). The -d option creates a database
               of E-mail addresses and the times an autoresponse was last
               mailed to them. Another autoresponse to the same address will
               not be mailed until at least the amount of time specified by
               the -D option has elapsed.

           -s "subject"
               Set the Subject: header on the autoresponse to subject.

           -n
               Show the resulting message, do not send it. Used for debugging
               purposes.
