see perldoc Mail::SpamAssassin::Conf
and specifically:
bayes_auto_learn_threshold_nonspam n.nn (default: 0.1)
The score threshold below which a mail has to score,
to be fed into SpamAssassin's learning systems auto
matically as a non-spam message.
bayes_auto_learn_threshold_spam n.nn (default: 12.0)
The score threshold above which a mail has to score,
to be fed into SpamAssassin's learning systems auto
matically as a spam message.
Note: SpamAssassin requires at least 3 points from the
header, and 3 points from the body to auto-learn as
spam. Therefore, the minimum working value for this
option is 6.

'db'??
You will see a test that starts with BAYES that will show up in the tests.
And remember, Bayesian Rules are just one test that will help determine if
email is ham or spam. SpamAssassin has literally hundreds and thousands of
rules available to test with and if you aren't using some of the network
tests look into them. I'm a big fan of uribl and surbl.
