> I turned off Bayes tests temporarily and it had little effect. This seems a bit odd. That bayes_00 should have been good for about -3 points. Backing out Bayes should have raised the scores on this stuff by around 3 points, which with only a little bit of help should be tipping them into spam.
On the other hand I was only seeing one or two other rules hitting on those things, which is rather few for a spam. You should maybe make sure that your paths to the rules files are what you think they are, and no rules files have gone missing. Running spamassassin --lint might be a good idea. You can also consider some add-on rulesets, like those at www.rulesemporium.com Loren
