Yes, well... Is this by any chance an image based spam? (I'm thinking
that would be a rethorical question, given the rule hits you have). If
so, look into implementing ImageInfo and perhaps FuzzyOcr
(ongoing/recent threads on this liost point you in the right
direction;-). Bayes has likely not that much to work with, so... that
would probably explain why it fires the _00 rule... And training will
not help you much with that type of spam...
