Message-ID: is supposed to uniquely identify a message - see RFC 2822.  It is 
possible to receive a message by two different routes.  In theory the body 
will be the same (not withstanding virus scanners and M$ Exchange's bizzarre 
charset handling) but the headers will be different - the Received: headers 
trace each route to the destination, others may differ too but the Message-ID 
should be identical.
