This is kinda techno-nerdy which might not match your user population very
well, but in many/most situations people should be able to look at the
Received: headers (when the personalization footer is absent) and work their
way from bottom to top to see what address of theirs is subscribed based
upon who it's being delivered to.  Here are the Received: headers I got from
your message, numbered for convenience:

The server running Mailman will probably talk directly to the MX host for
the destination domain.  In this case, "skip at pobox.com" appears in #3 while
the message is still on mail.python.org as well as in #4 once it gets to
