SYNOPSIS
pop3d [-c certfile] [-d] [-k keyfile] [-p path] [-t type]

DESCRIPTION
pop3d daemon implements Post Office Protocol (Version 3) as specified in RFC 1939 as well as POP3S and STARTTLS extensions.

pop3d binds to 110(POP3), 995(POP3S) ports and operates on local mailboxes on behalf of its remote users.

The options are as follows:

-c certfile
    Specify the certificate file. Defaults to /etc/ssl/server.crt.

-d  Do not daemonize. If this option is specified, pop3d will run in foreground and log to stderr.

-k keyfile
    Specify the key file. Defaults to /etc/ssl/private.key.

-p  Path to the maildrop. Defaults to /var/mail/%u in case of mbox and ~/Maildir in case of maildir. pop3d expands '~' to user's home dir and '%u' to user's name if specified in the path.

-t  Specify maildrop type. Options are mbox and maildir. Defaults to mbox.
