It sounds like you are either not using Bayes or it's not working well. If you use Bayes with auto-training it is liable to go "off the rails". If you're just filtering your own mail the best thing to do is to turn-on Bayes, turn-off auto-training, and train manually (running sa-learn as the correct unix user). Another thing is that if you do spam filtering, you should run your own non-forwarding DNS resolver. Shared caches can get blacklisted by domain and IP blocklists because they can go over the usage limit for a single IP address.
