I recently switched from SpamAssassin to an open source program called
DSPAM (http://www.nuclearelephant.com/projects/dspam/). It works
differently than SpamAssassin in that it processes each message that
comes in and creates a DSPAM Signature, which it puts in the header of
each e-mail, along with headers specifying whether it thought the e-mail
was spam or innocent, and the spam probability of the e-mail. DSPAM
starts off without filtering out anything, but the way it works is
through "training." You set up an e-mail alias for all your spam and
false positives on your server, and you forward spam that wasn't marked
as spam to the spam alias, the same for false positives. DSPAM then
checks the e-mail for any existing DSPAM signature, matches it against a
database, and records what you marked it as. It then uses the Bayes
algorithm of probability to detect any incoming e-mail's likeliness of
being considered spam based on your habits of marking spam.
It works extremely well, but it takes a while to train. I've had mine
up for three days now, and it is increasing in accuracy with each day.
You just have to make sure that you forward all your e-mails to the spam
alias when you receive them, and all false positives as well, or else it
will be worthless. Check out the web site, maybe it will help explain
it a bit more. One note - the documentation is not that good, so set up
could be a bit of a hassle.
