There are two obvious ways that jump to mind.

The first, which will address the bounce issue for all mail, is the
following code at the beginning of the process() function in

    # Calculate the non-VERP envelope sender.
    envsender = msgdata.get('envsender')
    if envsender is None:
        if mlist:
            envsender = mlist.GetBouncesEmail()
            envsender = Utils.get_site_email(extra='bounces')

which could simply be replaced by something like

    # Envelope sender (bounces) is always the site list.
    envsender = 'mailman at name.com'

Don't worry about VERP because it is calculated from envsender.

Another way to do it would be to modify the getListAddress() method
definition in Mailman/MailList.py to just return 'mailman at name.com'
when extra is not None and similarly modify get_site_email() in
Mailman/Utils.py to ignore the extra argument.

Then it might be possible to do it in your outgoing MTA, not with
aliases, but with some kind of rewrite of the envelope sender on
outgoing mail if your MTA supports such a thing.
