hi all,

a slightly off-track question:

my upstream smtp provider is already running an anti-spam solution and i therefore have messages coming in with a subject *** SPAM *** preceding the original subject, and the provider leaves me no solution to stop it.

i'd like to re-write the subject, eliminating the "*** SPAM ****" before amavis has a look at it and before it trains bayes -- bayes (i think) would start to notice that spam mails have a subject that is easy to
spot.

Yes, bayes would learn to trigger on the *** SPAM *** tag.

One workaround is to use
bayes_ignore_header Subject
in your spamassassin local.cf

Or you could use postfix header_checks REPLACE action with something like:
/^Subject: \*\*\* SPAM \*\*\* (.*)/     REPLACE  Subject: $1
