Rudy,

I've been using SpamAssassin on my mail server for a couple of years
and have great success with it.  I train it daily with SPAM which
gets missed.  I ask my users to attach mail (complete with all
headers) to an email and send them to a special address which then
gets picked up and fed to sa-learn.  I also train the filters with
non-SPAM.
$ man sa-learn

The other thing I do is to (automatically) update the rulesets I
use.  Because spammers constantly change their methods, the rulesets
are often updated regularly.
