Look at the full headers of the messages they receive. If list messages
are VERPed, the envelope sender (usually reflected in a Return-Path:
header), Sender: and Error's-To: headers all contain the address sent to
(with '@' replaced by '=').

Also if the list is personalized, you can put something like

Sent to: %(user_delivered_to)s

in msg_footer to expose the address sent to (if %(user_optionsurl)s
isn't alreader there).

Also, it's not likely, but another possibility is there is another
mailman instance sending these messages. The Received: headers should
contain clues to this.
