I have only been doing this for about a month, so I don't have
a lot of experience with it. (but that's part of the reason I
wanted to try it, to see how well it works, or doesn't.)
Before I started doing this I checked my existing mailboxes for
stuff with SA score > 10, but I just realized that I hadn't been
running spamassassin on list mail in the past, so that test was
Checking my current exim4 rejectlogs (10 days worth), there have
only been two messages rejected from mailman-backed lists, both
I don't know for sure, but I think most list software doesn't
kick you off due to a stray bounce here and there. But I should
modify my SA config to whitelist known lists or something.
I realize there's a risk that I'll end up bouncing legitimate
messages once in a while, but I decided I'm better off that way
than silently filtering and ignoring it. I remember once in the
past I got snail mail from Etrade or Datek or someone saying
"hey dude, your email is bouncing"; if I filter+ignore their
mail, they have no indication at all it wasn't received.
