This mailman installation has non-standard patches/code.

In standard GNU Mailman, both Errors-To: and Sender: as added by Mailman
will be to the listname-bounces address. Here they go to -owner and
-request respectively, so the most likely explanation for multiple
Sender: headers is the installation's modified code doesn't remove the
Sender: headers before adding its own.
