we can't really tell since we didn't see the messages that made it through postfix+friends. if the messages contained a URI listed at uribl or surbl, then you could try using uribl/surbl via milter-link or via spamassassin (via amavisd-new). anyway, You can add spamassassin (via amavisd-new) to your chain and see if it improves your filtering. at one time, the question becomes: is the additional effort worth the pain?
