the issue is: will you maintain this? if you can maintain it, then it's ok. but if you think you'd better let spamassassin team work on that, then remove your own checks and rely on SA updates. in fact, the hard part is spam that other users get. and harder is the FPs you create (when your users miss a legit mail because of one of your rules). so if I have a recommendation, then it'll be: don't try to stop all spam. try to make the spam users receive to a manageable limit. don't over react. don't try to stop every spam.
