In most cases I use spamassassin.
However my main defense line is spamhaus and spamcop.
On spamcop I use also their service to submit complains. This is
really nice, they will send a notification to the admin mailbox.
And it often really works.
with the two DNSBL I pretty much filter 90% of all spam.
Spamassassin almost gets the rest and a few hit the actual mailboxes.
With spamassassin it is very important for your users to understand
the difference between unwanted mail a unsolicited mass spam when
they submit for training the system.
In some cases I block complete regions (geoip blocking). This
obviously works only for "local" mailservers.
But if you business doesn't have international clients, dropping
ru, tw, hk, br lowers the traffic by 80%.
