Rise up bayes tests

[Paolo De Marco <pa...@realcomm.it>]

Hi.
Sometimes only bayes tests hit mails, so i recieve mail whit only bayes 
point (for exemple: X-Spam-Status: No, score=3.5 tagged_above=-999 
required=5 tests=[BAYES_99=3.5])
Does anyone raise up the score of bayesan test? Is it safe?

IIUC the main problem with higher score is that many people don't know how
to train bayes properly, and then often treat unwanted messages (e.g. from
mailing lists they have subscribed to) as spam.

however the scores 3.5 for BAYES_99 and -2.6 for BAYES_00 are often treated
as too low and I've seen many requests to make them higher (in absolute
value). The problem with adjusting scores is that when someone starts doing
it, many things can happen...

afaik it is not recommended to raise the Bayes Score
You could do it but keep in mind if bayes is "misguided" your higher 
score hits.
(With a well trained bayes it seems reasonable to me)
Perhaps you could find some additional rules/network tests ...
(sare-rules, razor, dcc, pyzor etc (watch licenses if you could use them)).

On new "few lines text" spam i often get bayes_00 so it is not always 
useful.
