I have a similar issue... and I was wondering if anyone responded on this
thread... I would like to know if others are changing the bayes* scores...
I know I have wrote about 100 custom rules, and changed about 50
points.....but i haven't touched the bayes yet... mostly because I haven't
a good way to use sa-learn on my gateway mailrouter boxes yet... (internal
users are  lotus notes users, and it doesn't support forward as attachment

So, is anyone else doing this sort of stuff?

I'm getting quite a number of spam messages that just sneak under the
threshold of 5.0. While I'm tempted to just decrease the threshold, I don't
want to increase the number of false-positives either.

I notice that in each of these messages, Bayes_90 is triggered, but that
adds 3.0 to the score. If Bayes is 90% certain that this message is spam,
should I "trust" it a little more by say, giving it a 4.0 weight instead of
