[SAC] Mailman spam filtering?

[Jason Birch]

I've seen variable results with greylisting.  It works fairly well, but
I've also seen a few cases of legitimate users with badly behaving MTAs
that never get their messages through.  If we're willing to accept those
edge cases, then it's a great first-pass filter for spam.

Something like greylisting is really easy (2 min installation) and drops
90% of rubbish:

In case we use postfix, this could be a first approach with rather 0
effort.
