Mailfilter - The Anti-Spam Utility

General Information:

Mailfilter is a flexible utility for Unix (-like) operating systems to get rid of unwanted spam mails, before having to go through the trouble of downloading them into the local computer. It offers support for one or many POP accounts and is especially useful for dialup connections via modem, ISDN, etc.

Mailfilter connects to any POP mail box and compares part of its content to a set of user defined filter rules. That way the spam gets deleted directly on the mail server.

With Mailfilter you can define your own filters (rules) to determine which e-mails should be delivered and which are considered waste. Rules are regular expressions, so you can make use of familiar options from other mail delivery programs such as e.g. procmail.

Mailfilter is released under the terms of the GNU General Public License. For more information, see the README and COPYING documents provided with the Mailfilter program.
