Start off by comparing Message-ID: headers.. If the message is a dupe occurring
at the MTA layer, they should be the same. If they're different, some piece of
software that thinks it's at the client level re-generated the message (ie: a
auto-forwarder rule in a client).

Follow up with comparing the path in the Received: headers. Do they differ at
all? If so, one of the servers involved in the difference is responsible.
