Today the only spam which slipped thru was a short one with some URLs in
HTML and then this at the end (see below):

I think this is not only trying to trick Bayes in thinking it's ham but
also tries to spoil the Bayes ham recognition if I teach that message as
spam to sa-learn because Bayes will now add some spam percentage to BEGIN
PGP SIGNATURE or "rocky" or "comparing" etc.
Or am I wrong?
What should I do? Teach the complete message to Bayes as spam or remove
this stuff before teaching it?

I opted for resetting the bayes database every couple of weeks - this
kind of thing tends to make bayes more and more deranged...
unfortunately it seems to be a weakness of the bayes method.
