One thing to try, that's fairly painless, would be to make use of the
SA option bayes_learn_to_journal. From Mail::SpamAssassin::Conf(3):
bayes_learn_to_journal (default: 0)
If this option is set, whenever SpamAssassin does
Bayes learning, it will put the information into the
journal instead of directly into the database. This
lowers contention for locking the database to execute
an update, but will also cause more access to the
journal and cause a delay before the updates are actu?
ally committed to the Bayes database.
Along with doing "bayes_learn_to_journal 1" you should also look at
setting these:
bayes_auto_expire 0
bayes_journal_max_size 0
After doing this, you'll then need to establish a cron job to manually
sync/expire the Bayes DB files. Essentially it just needs to do the
following as the MIMEDefang user:
sa-learn -p /etc/mail/spamassassin/sa-mimedefang.cf --force-expire
I run this once a day at a time when there's likely to be little mail
traffic.
