Since you're now sending just one message for each recipient, you will get 
unique queue ids assigned by your MTA for each and every message, and most 
MTAs will record those in the "Received:" headers.  You seem to have found 
what looks like a unique queue id from postfix, and that should lead you to 
one and only one message.

You might also get unique message-ids if you're doing Full Personalization, 
but that shouldn't be necessary in this case.
