Look at the tar ball and it has a statistics file in masscheck, that lists
the fn/fp for each score level.
Mail-SpamAssassin-2.63/rules/Statistics.txt.
it's alright if your bayes database has a few miss-learned email in it,
the bayes will adjust for it.
Set set your learn hamd/learn spam levels good enough so you have very few
miss learnings.
I throw in pyzor/dcc/razor and on average that knocks the average score
upt to 17.5.
This is the average score for all email that scores 6 or higher, so is not
the actual average score.
In my case I'm only catching around 65%-70% of the incoming spam, but I
have too high a mail volume to relearn, nor can I have individual user
preferences. I catch more of the mail at the second SA install, which has
more customized installs.
I was too afraid of fp to use the sare rules except for:
backhair.cf, and randomword.cf, they both work well.
randomword.cf for bayesian poisoning.
