_any_ spam filter can have false positives. If there was spam filter that
would have no false positives (and would block all spam), there would be no
spam anymore. If it would not hit any spam, all spammers would change their
spam not to hit that one.

Spamcop is perfectly good, if properly used. and I think it's perfect even
at SMTP time...

training bayes filter should help you much. If you notice any false
positives, you can use whitelisting ot increasing the required score.
