Hello Duncan,
Since I have upgraded to 3.1.0a-1, bayesian filtering is far less
efficient than with the sarge version or 3.0.4.

Symptoms are a ton of spam with BAYES_50, sa-learn not increasing
the bayesian probability most of the time (but some time it does)
seen by spamassassin -t, and an overall increase of false-negative.

I tried sa-learn --import, but it was apparently a noop.
sa-learn --lint did not complain either.

I installed a sarge chroot to test: Sarge sa-learn and spamassassin
seems to perform much better with the same spams and the same bayesian
database and the same configuration.

(Read the report at the listed URL for more detail)
