NAME
mailbot - MIME-capable autoresponder utility

SYNOPSIS
mailbot [options] program arg arg...
.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 a message on standard input, then mails an autoresponse to the sender. The autoresponse is mailed by running program that's specified as an argument to mailbot after all the options. If 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 "Precedence: bulk" header, or if's MIME content type is "multipart/report", which is used for delivery status notifications. The autoresponse itself will be a delivery status notification if the -M option is used.

  OPTIONS

-t filename
    read text autoresponse from filename, which should contain plain text.

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

-m filename
    like -t except that filename contains MIME headers, followed by a blank line, then the corresponding MIME content. The contents of filename are inserted in the autoresponse without further processing.

-M address
    format the autoresponse as a delivery status notification (RFC 1894). address is an RFC 822 E-mail address that generates the DSN. Note that the -A option should be used in addition to -M in order to set the From: header on the autoresponse.

-r addrlist
    addrlist is a comma separated list of RFC 822 E-mail addresses. mailbot will send an autoresponse only if the original message has at least one of the given addresses in any To: or Cc: header.

-d filename
    create a small database, filename, that is used to prevent duplicate autoresponses going to the same address. The -d option is only available if maildrop has been configured with GDBM/DB extensions.

-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.

-A 'header: value'
    add an arbitrary header to the autoresponse. Multiple -A options are allowed.
