Have you looked at the STATISTICS* files?
Not recently, but when I look at them now, I'm not sure that I can interpret them in the context of what we were discussing ;)

All Bayes systems will get skewed if you bias the learning one way or the other, 2.60 hasn't changed that.
As for the autolearn values, people may have to change it (and other default values) as necessary. We try to make the defaults generically good for everyone, but everyone's situation is different. :)
Of course..

If I could tell the future, I'd be winning lotteries left and right. ;)
Except this is a lottery where you're selecting the balls ;)
I would assume it won't be reduced below 50. The idea was that 50 should be high enough for anyone to know "ok, this is spam, really." I can't see why we'd lower it right now.
