Mailmunge is a mail filter based on the Sendmail Milter  filtering protocol and library. This protocol is used by both Sendmail and Postfix, allowing Mailmunge to work with either Postfix or Sendmail.

Mailmunge connects the Milter protocol to a set of Perl worker processes. This lets you write your mail filtering policies in Perl, and make use of the wealth of CPAN modules available for dealing with MIME and email in general.

Mailmunge is Free Software, licensed under the terms of the GNU General Public License, Version 2. It should work on any reasonably-modern UNIX or Linux system running Postfix or Sendmail.
