Removing files from "TRUSTED_RULESETS" in /etc/rulesdujour/config
doesn't remove them from /etc/mail/spamassassin. Once you've
removed a ruleset from the config file, then manually delete it from
the spamassassin directory.
That means, after I remove a rule in TRUSTED_RULESETS, i have to remove the
corresponding file(s) manually. Am i right?
I'm not sure about your first question.
Because i saw some message with very high score (>30). It would be nice to stop scanning when the
score reach certain level(e.g., 15). But i dunno if it's possible.
