SpamAssassin gone wild!
It seems that lately SpamAssassin has had a bit too much fun marking mail as spam with the ‘BAYES_99′ rule. This seems to have started recently when the Bayesian spam DB was upgraded from MySQL 5.0 to 5.5. Exactly what went wrong… well I am still working on that. For now, Bayes processing is disabled for all GeekISP accounts until I can get to the bottom of it.
