that's too much and gives even a message on systems where
BAYES_99 and BAYES_999 would reach 8.0 a negative score
Do you have any evidence for it being too much? It seems about right
to me.
If you have an actual problem I'd suggest you use unwhitelist_from_dkim
locally and report the domain so it can be considered for delisting.
The dkim default whitelist contains domains that send a lot of
autogenerated and bulk mail, but have a very low probabilty of sending
spam
how can -7.5 be right?
it bypasses unconditional any bayse regardless if it is trained
with 100, 1000 or 10000 messages ham / spam and that can not
be the the right thing
That's kinda the *point* to a whitelist.
I would suggest getting BAYES_999 on a message that has a valid DKIM
signature for a domain in the default DKIM whitelist may instead indicate
either bayes mistraining or somebody has put something into the default
DKIM whitelist locally that they shouldn't have.
Would you care to share the spam that you posted the scores for at the
start of this thread? There's not much we can do with just the rules that
hit beside post vague guesses. The critical part is: which domain is that
whitelisted DKIM signature for?
Is it possible that your bayes has been trained with legit[1] newsletters
that someone is dropping into their spambox rather than unsubscribing
from?
[1] "legit" meaning that the person actually subscribed to, or from a
sender that the person actually is a customer of or does have a business
relationship with.
