[Mailman-Users] Rewriting or identifying late bounces

Hello world,

some of my list members have a mail address like recipient at example.com
- nothing special about that. When mail is delivered to their address,
their ISPs mail server rewrite the address internally to
recipient at intern.example.com and try to deliver them to the users
mailbox. If for any reason, e.g. quota, this fails, a NDR/DSN is sent
with the new name:

Received: from mout3.example.com (mout3.example.com [195.4.92.93])
    (using TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits))
    (No client certificate requested)
    by mail.incertum.net (Postfix) with ESMTPS
    for <invalidlist-bounces at lists.incertum.net>; Tue,  7 Jul 2009 23:09:54 +0200 (CEST)

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

  save to inbox
    generated by recipient at intern.example.com
    mailbox is full: retry timeout exceeded

Is there any way to rewrite those addresses or to help Mailman
identify those bounces correctly?

And yes, this a pretty stupid thing to do on their ISPs part...


Ciao
Stefan
