I’ve decided to go public with my current version of my installation guide for DSPAM. Although it’s not quite finished and it still has some rough edges and I still need to add some features. It’s polished enough to get you a working version running on your mail-server which will eliminate quite a surprising amount of spam. You’ll need to train DSPAM to get some good results, use it a week and you’ll be amazed by it’s performance.
For instance: almost all stock selling spam (the ones with the image spam) get’s tagged as spam . If a new version of spam appears I just need to train DSPAM with a few examples and from then on they are identified as spam.
The setup I’ve currently chosen is to include DSPAM as a content filter for Postfix. This means that mail enters Postfix, is then fed through DSPAM which tags the emails and feeds it back into Postfix to have the emails delivered into the users maildir. Spam is indicated by some header tags but also the tag [SPAM] is added to the subject to be able to use a filter on my email client. DSPAM is trained by putting the missed spam messages into the users Junk folder on the IMAP server. A script that runs overnight feeds them to the DSPAM training program.
One of the features I want to add in the near future is to use maildrop to drop spam messages into the users Junk folder.
Read all about installing DSPAM using my existing mailserver setup in the documentation.
I hope you enjoy the benefits of DSPAM as well as I do.
