BAYES_99, by definition, has a 1% false positive rate.
That is what Bayes thinks. I think it is closer to something between
0.5% and 0.1% false positive. I have mine trained down lethally fine
at this point, it appears.
Ok.. Fine, let's take 0.1% FP rate, 10x better than theoretical, but
still realistic at some sites.. Even still.. Is that low enough to be
worth assigning >5.0 points to?
No.
So far, however, it has been worth 5.0 points. I've had it (actually)
false positive maybe once in the last month. I've had SA mismark some
BAYES_99 spam, however. The spam had other characteristics that earned
a slight negative score.
(I've since developed some meta rules that are reducing this. It the
email is from a mailing list I know I give a modest negative score.
Then if the Bayes is high or very high I award some positive points.
High plus mailing list is about 2 points with mailing list being -1.5.
Very high adds another 2 points. That second two points MAY have to be
fine tuned upwards.)
