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.
