I can not agree here. German spams are not catched at all. Without additional
rules german spam comes through unfiltered. We use the excellent german ruleset
http://www.exit0.us/index.php/GermanRules with some additions and corrections.

You also want to catch the stupid 'virus has been removed messages' for
netsky and friends. See http://www.exit0.us/index.php/RulesDuJour.

Additionally we experienced that the bayesian filter slows down
after ~ 1000000 mails and gets ineffective, especially for english
business mails. There needs to be a way to use autotraining and clean up
old stuff. Maybe I should RTFM :-)

The RBL's are the most important thing to use. And the second thing we use
is a list of spam advertized sites collected by ourself. Currently we have
7500 sites in there.
