I don't think so -- not within Mailman, at least. But your MTA
may well be able to be configured to do something like this,
depending on the MTA.

Mailman does attempt to prevent copies of messages being sent to
addresses that it can see on the To: and Cc: headers, but if a person
has multiple different addresses and one is subscribed to the list
and another is displayed in the headers, there's nothing that Mailman
can do for you.
This problem would need to be resolved with a tool like procmail,
on the recipient system.
