[courier-users] SPAM filters (was: mail queue purge)

I use the Spamhaus and Spamcop blocklists, SPF, clamav, spamassassin,
razor, pyzor, and dcc.

Courier can be easily configured to use blocklists. They stop known
SPAMmers from even getting a message on the server.

SPF is tricky. Because not everyone has implemented it, you have to
accept everything except mail from hosts that thoroughly fail SPF. It
stops many phishers in their tracks.

ClamAV gets rid of many phishing emails in addition to virii.

Spamassassin will call razor, pyzor, and dcc if it finds them on your
machine and use their input to make its decisions.

Other than that, I've tried Bayesian SPAM filters, but didn't like
having to keep large archives of SPAM around to retrain them every once
in a while.

Hope this helps,
