I haven't trained my bayes, it seemed complex when I last looked.
The "BAYES_00" in the rule hits above strongly suggests that mistrained
Bayes is the primary culprit (if this is indeed a FN).
If you haven't trained bayes, then return your required score to 5 and
disable Bayes and see if it behaves better.
Then, collect a few hundred ham and spam messages, wipe your bayes
database, train it properly using those messages, and reenable it.
Training is pretty simple. All you have to do is collect representative
ham and spam messages in a couple of mail folders, and tell sa-learn to
process them. The critical bit that usually causes problems is you must
run sa-learn as the user that the MTA is running spamassassin as, or make
sure that your configuration defines a system-global Bayes database.
You will probably want to set up a nightly cron job to run sa-learn
against your ham and spam corpus folders. Then you can just add
misclassified messages (spams from your inbox, and hams from your spam
quarantine) to those folders as you encounter them.
