Spam Filtering with Procmail

Current version: 20030115

About junkfilter

junkfilter is a procmail -based filter system for electronic mail. Procmail is a popular and powerful mail-processing program available for nearly all Unix systems. This means that junkfilter doesn't work on Windows, AOL, Hotmail, Yahoo! Mail, Juno, WebTV, or any other type of system--just Unix (BSD, Linux, Solaris, etc.).

junkfilter filters a wide range of spam using many different types of filters. It is configurable on a systemwide or per-user basis. Is unsolicited commercial email (UCE) filling up your mailbox? Can't stand the thought of webmail-style throwaway email addresses? Take control of your inbox: filter out 90+% of that spam with junkfilter.

Copyright and Terms of Use

Obtaining junkfilter

I strongly suggest that you read the README file before you download or try to install.

Then you can:

If you are a FreeBSD user, you may want to use the FreeBSD port/package of junkfilter instead.

You can also download older releases, but I really don't recommend it.

Help Improve junkfilter!

Help improve junkfilter! If you know procmail, or would like an example of a working procmail-based tool of medium complexity to play with or hack around on, take a look at the junkfilter code. There are lots of ways to improve the system. Please submit bugs (and preferably patches) to the management systems at SourceForge:

bugs:
http://sourceforge.net/tracker/?atid=113498&group_id=13498&func=browse

patches:
http://sourceforge.net/tracker/?atid=313498&group_id=13498&func=browse

Bugs, patches, questions, and comments may also be posted to the junkfilter-users mailing list or to the author. Note that emailing the author directly has the lowest probability of receiving a timely response.

If you can't use junkfilter

(If you don't have procmail or access to procmail (through a shell account on your ISP), you could try Myles White's filtering strategies for popular programs such as Eudora, Outlook, Netscape, and Pegasus. They're not as good as procmail, but they're a whole lot better than nothing.)

Contact

I hope the junkfilter junk mail filtration system is of use to you. Please contact the author for more information.
