    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.
