So if a message is addressed To a mailing list you're subscribed to, and Cc'd to you, then your incoming mail server will receive two copies of the message.

As I alluded to earlier, Mailman does have a per-user setting[1] for preventing duplicate messages. It scans the Cc list for the addresses of list members who don't want dups and simply doesn't deliver anything to those addresses.
