I did say above "some are my own scoring". I've been evaluating BRBL to
see if it's a candidate to use at the smtp level and need to identify
possible false positives. Giving it a ridiculously high score ensures
any hits end up in quarantine where I can examine. No FPs of note yet.
I've also tweaked the Basian scoring for my own preferences. I still see
a fair amount of spam caught by Bayes alone and manually train Bayes
with confirmed ham/spam only. I have high confidence in my Bayesian
setup and whitelisting invariably catches any potential FP hits.
In general, I wouldn't recommend users tweak the default scoring too much.
