We use SpamAssassin for several clients here in Qatar , As a company providing several types of anti-spam solutions we can easily certify that SpamAssassin has the least number of false positives compared to its commercial counterparts like Barracuda and Sonicwall . SpamAssassin is the only solution you can use if you want to relay emails ( smarthost ) to an smtps server ( ofcourse with stunnel and postfix ) , most of commercial appliances doesnt support this feature .

SpamAssassin is an amazing product. When I first started spam filtering in 2000 I tried using some crude Exim rules. I remember thinking that if I could accurately get rid og 80% of spam that would be good enough. I though that nothing over 80% was theoretically possible. Then I discovered SpamAssassin and now - along with a lot of other tricks - I'm getting rid of better than 99% of spam without false positives. SpamAssassin is the central scoring engines that makes it all work.
