UnixReview.com: The Open Road: Procmail Feb 13, 2002, 15 :03 UTC (2 Talkback[s]) (4809 reads) (Other stories by Joe)
"This month, I'm going to look at filtering mail with Procmail. There are many reasons to filter your mail. For example, I subscribe to several mailing lists and get email from several different accounts; some of that mail is fairly important and some isn't urgent at all. And, of course, there's the ever-continuing battle against spam.
Most Mail User Agents (MUA) include some kind of mail filtering, but none of them holds a candle to the flexibility and power of Procmail. Procmail is one of the most powerful programs for filtering and processing email, but the syntax used by Procmail is not exactly intuitive. However, once you've overcome the hurdle of understanding the syntax used to create Procmail recipes, you'll be very glad you did.
If you're using Linux, the odds are that Procmail is already installed on your system. If you're using a different *nix that doesn't include Procmail by default, you can find the latest version at http://www.procmail.org. There is also a mailing list for users as well as an announcement list. Remember to grab the code from a mirror rather than the main site whenever possible."
