ezmlm-managed lists do as well, but it's married to qmail, which
might not be useful for you...

As described on other lists, you'll need to be able to generate a
message for each recipient with their subscribed address somehow
encoded in the envelope sender address, such that when a bounce
returns to the list manager, that software can extract it.

Under the qmail universe, such a construct is called a VERP (Variable
Envelope Return Paths):

As far as I know, ezmlm was the first MLM to handle bounces in this
manner, but many other MLMs now utilize similar features...

In fact, a Google search on 'VERP' reveals many hits for other MTA/MLM
combinations.
