Extending SpamAssassin and Amavis

An anonymous reader writes "Spam filtering solutions are a necessary evil in today's e-mail climate. There are many different tools and systems available for the filtering and removal of spam e-mail. Tools like SpamAssassin and more detailed agents, such as Amavis use a variety of different methods to identify and capture spam. An IBM article shows how you can extend SpamAssassin and Amavis, providing additional filtering facilities to lower the amount of spam hitting e-mail boxes."

Re:What a useless article.

Anyone that's done much exploration of spam filtering already knows the basic architecture of self-learning filters. This article has nothing new.

Well, since Amavis/Spam Assassin don't do what the article addresses out of the box, much of what's listed in it is useful. However, anyone interested in this article should probably check out Maia Mailguard [maiamailguard.com], which does most of what the article talks about and much more, with a web interface.

Recently I've implemented greylisting on my mail server. The drop in spam has been enormous, though there have been a couple cases where email didn't go through on the first try.

Yes, greylisting is nice. However, this has nothing to do with Amavis/SA. Greylisting is another technique that one would use along side SA.
