[Mailman-Users] Basic requirements for bounce processing

[francis picabia]

I'm looking for the high level view on what is
needed for bounce processing to be available.

I'm running mailman 2.1.12-18 from Redhat 6.

Under the Bounce processing heading, we have Yes.
MTA is Postfix.

Now what happens?  I check an email from the list
and I don't see a "-bounces" anywhere in the headers.
Everything is from "-owner".  Am I missing a setting?
