In your experience, what is a good ‘certain spam’ threshold? By that I
mean the score above which messages are virtually always spam, no false
positives.
basicly all above 5 is spam tagged with default spamassassin, it is so
as long as spamassassin does only tags mails, eq spamassassin is not
designed to ever reject any emails
The default threshold for spam is 5.0, which works well for me. Only
very rarely a ham message scores above that and lands in my Junk
folder.
Would 10.0 be a good ‘certain spam’ threshold? 15.0? I could then
reject
such messages at the SMTP layer, without having to worry about
rejecting
legitimate messages.
in fuglu i use 15 as reject score, it can be done in spamas-milter
aswell, but its not spamassassin fault, in many places of score in
spamassassin its for negative spam -100, and for possitive spam +100,
both can be changed scores on so it never reject fp
spammers knows defaults scores so thay hope recipients never change it,
spammers want whitelist_from * but in mta stage local recipients is not
evelobe senders, so whitelist in spamassassin is still safe to use where
its needed, but remember dont if not needed
i begin to see to make rules scores safe it must not exists a single
rule with score above 3, but there can be multiple rules to add more
score, this is more safe to do then a single rule with 30+
