Spamassassin can be configuredt to use razor. We use bayesian rules, some 
downloaded rules, my own custom rules, razor and dcc (Distributed Checksom 
Clearinghouse) in determining the spam score for a message.

I have not seen a false positive in my own mail and no user has reported a 
false positive for about 2 years. And I probably catch about 98% of spam.
