The problem here that you're stating "it's an unattended server system". E-mail and spam change all the time, you cannot have great filtering without adjusting to new trends and threats. Using bayesian filtering is an easy way to improve detection, because you only need to decide whether mail is ham or spam, and the bayes engine does most of the other hard work for you. If you're not going to put in some effort to either train a bayesian filter for your users, of enable them to train it themselves (this has some risks you should be aware of), your filtering won't improve. But on the other hand: trying to write your own SA rules in order to block mails in a language you don't even understand is a lot harder.
