I am trying to figure out which rulesets are important to me, and which ones aren't.
I am probably up to about 90% of my spam being trapped, but still, some very significant ones make it through, so I am trying to tune my rulesets. The other thing is that the filtering is causing pauses in my use of KMail. I would love to shorten or end the pauses.
Hmm.. does your setup by any chance log your message statuses anywhere (ie /var/log/maillog)?
Really the quickest way to post-delivery evaluate is to use something like this:
grep RULE_NAME maillog | wc -l
Repeat for each rule and see who's making the most and the fewest hits.
You could probably do the same thing with kmail's mailbox files, although it would be slower.
However, this won't really tell you which are "important" in the sense of which ones made the difference between a FN and a hit. It will just tell you which ones are getting hit the most. Determining which ones made a difference is more-or-less a by-hand process.. I usually look around for low scoring spam, then look at the rule hits of those..
