Rules statistics and custom values

[Francesco Abeni <f....@gibilogic.com>]

Good morning everyone.

I'm using succesfully SpamAssassin to filter spam. It is already good, 
but there are still false positives. I checked their Spam Level one by 
one and get a maximum of 6.7. So i increased "required hits" from 5.0 to 
7.0, to eliminate false positives, but of course this means that more 
spam is not identified.

What i'd like to do is compare ham and spam messages with similar Spam 
Level, to check which rules are applied in one case or the other, to 
adjust manually the values of these rules in case there is an evident 
pattern.

My question is, does anyone know of a tool that can give me this "rules 
usage" on a folder of messages?

Mass-check does this. It, combined with the hit-frequencies tool is how 
the STATISTICS-set*.txt files are generated (see them in the rules 
subdir of the tarball)
