Thank you, "J", for the suggestion,
but that seems not an option for two reasons

1) we (currenly must) use sendmail and that doesn't seem to
   support VERPing -- or at least we haven't found docu on that

2) VERP will probably cost quite a bit of CPU/memory/disk-IO
   resources on the mail servert.  Currently that server almost
   constantly runs on load 2.5 -- 3 
    (because of anti-virus / anti-spam / mailman ..)

------

OTOH, most of these "uncaught bounce notification" can quite
easily resolved by a human, i.e., the subscriber's e-mail can
very often be found in the bounce.
E.g., if they resend the full headers, I can find the proper
subscriber's address in a "Received:" header such as

Received: from hypatia.math.ethz.ch ([EMAIL PROTECTED] [129.132.58.23])
        by cryforhelp.mr.itd.umich.edu (umich) with ESMTP id hAB7NrHc014893
        for <[EMAIL PROTECTED]>; Tue, 11 Nov 2003 02:23:53 -0500

(hypatia is our own mail server)

I.e., I think mailman's analysis of the bounce message leaves
room for improvement. Can you tell me where in the python code
this happens (so we might consider improving it here)?

Best regards,
and thank you all for mailman!
