mimedefang uses spamassassin. I also use spambnc. All combined are very effective. The idea is to block/classify messages when they arrive at the server, so the clients can avoid the nasties. One problem, unavoidable, is false positives, where a message that is desired looks like spam. With some tuning this can be gotten very rare, but never perfectly eliminated. So I put rejected messages into a spam file rather than just dropping them, and do a quick scan once in a while to catch things incorrectly blocked. But the tuning probably needs to be done per-user, by the user, so is not practical for non-technical users. mimedefang does perfectly its main job of removing executable attachments without any tuning. But that's not blocking spam.
