SUBJ_ALL_CAPS=3.1,UPPERCASE_75_100=1.528
Does this indicate that bayes needs tuning/learning?
Can you paste the output from "sa-learn --dump magic" ?
It probably indicates that Bayes has been mistrained - somebody is
training spammy messages as ham.
How do you do your Bayes training? Autolearning, or purely manual, or some
combination?
How many messages are getting inappropriate Bayes scores? If a lot are,
you'll probably want to turn off autolearning (if you're using it) until
you analyze the problem. You may need to wipe your Bayes database and
start fresh if the problem is bad enough.
If you're using autolearning, what are your learning thresholds?
If you're manually training, do you keep your corpora so that you can
review and correct errors? If so, review your ham corpora and see if any
spams have crept in - and if so, retrain them as spam, SA will forget that
they were hammy.
