Are you using Mailwatch?
It makes it easy to get bayes to forget some mails. I archive everything
for 2 weeks, and that way I can reverse any weird auto learned stuff.

Here is something I added to my spam.assassin.prefs.conf file for the
Geocities spam.

uri PROLO_GEO_CHECK1 /^http:\/\/.*\.geocities\.com\//
score PROLO_GEO_CHECK1  5.0

Got it from the list, and modified it to hit all geocities, and not just
uk and italy. Change the score to suit your situation.
