Extending SpamAssassin and Amavis

Posted by Zonk on from the they-look-totally-natural dept.

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."

  1. Our just use GMail... by daveisfera · · Score: 2, Interesting

    Or you could just use an email provider like GMail that has good spam filtering and let them worry about it.

  2. I said it once, and I'll say it again... by siyavash · · Score: 2, Informative

    I know this solution isn't fit for "average user" but I use white list aliases, when I write my email in some website or whereever, I do @domain.com , as soon as I start to get SPAM, two things happen :

    1. I know WHERE the SPAM is comming from and who rat my email out.
    2. I can close that specific alias and no more SPAM.

    Using the above technique, I see ZERO SPAM... like good old days of emailing.

  3. Flexible smtp daemon? by r0.ini · · Score: 2, Informative

    If you need a real flexible smtp daemon, and can program in perl, I would recommend qpsmtd. Give it a try, you can create your own plugins (to handle spam or whatever you need) so easily you won't believe it.

  4. Re:What a useless article. by falzbro · · Score: 2, Insightful

    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, 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.
