That's a good point, even though current RFCs (RFC3464, RFC3834) say
that DSNs and and other automatic responses should go to the envelope
sender of the original message, not the Sender: address.

Actually, in Mailman 2.1.x, LIST-admin is a deprecated synonym for
LIST-bounces so we could just put LIST-admin in the Sender: header
(and "undeprecate" it) and nothing would change except

I'm not sure I understand the following:

Presumably, a CCd post would not be recognizable as a DSN, so whether
it was sent to LIST-admin, LIST-bounces or LIST-owner, it would end up
going to the human owners/moderators at least if
bounce_unrecognized_goes_to_list_owner is Yes.
However, if the Sender: were VERP like as in
LIST-admin+rcpt=example.net at list.example.com, the return could be
recognized, but I think that defeats the purpose of having a non-geeky
If the issue would truly be resolved or at least mitigated by having
the Sender: be LIST-admin at list.example.com instead of
LIST-bounces at list.example.com, that's a really easy change that
wouldn't have any unintended side effects.
