> the small number of ham hit with a -1.0 threshold (about 1.21% of ham
> mail according to mass-checks, see bug 5257) should be no problem to it.

If the change of a threshold to -1.0 was intended to reduce the number
of ham message fed into bayes, in my view it is a wrong solution to
the problem. Moving a threshold into gaussian periphery results in a
skewed/distorted view being presented to autolearning.

If the only intention is to reduce the amount of ham fed to autolearner,
some decimation can be used, like comparing a random generator value
to some threshold, say 0.2 would keep every fifth ham on the average
for autolearning and ignore the rest.
