You can also adjust the threshold at which SA will autolearn the message
as spam (but there is a caveat, see below). From the
Mail::SpamAssassin::Conf man page (reformatted):
bayes_auto_learn ( 0 | 1 ) (default: 1)
Whether SpamAssassin should automatically feed high-scoring
mails (or low-scoring mails, for non-spam) into its learn
ing systems. The only learning system supported currently is
a naive-Bayesian-style classifier.
Note that certain tests are ignored when determining whether
a message should be trained upon:
- auto-whitelist (AWL)
- rules with tflags set to 'learn' (the Bayesian rules)
- rules with tflags set to 'userconf' (user
white/black-listing rules, etc)
Also note that auto-training occurs using scores from either
scoreset 0 or 1, depending on what scoreset is used dur ing
message check. It is likely that the message check and
auto-train scores will be different.
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 automatically 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 automatically 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.
