Load up SpamAssassin (http://spamassassin.org) and get the add-on rules
at RulesEmporium (http://www.rulesemporium.com) then integrate it to
your MTA. Works like a charm to me. It cut down the spam by 90+% with
very small number of false positives. The key is to run it for a week
and tweak some scores to match your environment; for example, if you're
a pharmaceutical company you wouldn't want SpamAssassin to aggressively
knocks out any mail with drugs name in it.
