	This may be an MTA problem.  You need to get complete copies of 
all the sample messages (including all headers intact), and then 
compare that against your log information.  Specifically, you're 
looking for message-id, and queue-id information (queue-ids are 
usually shown in the "Received:" header).

	You want to compare and contrast all copies of all sample 
messages to see if they share the same message-id but different 
queue-ids on your machine (or some machine downstream from yours), or 
if the message-ids are also different, etc....


	This may be the result of a problem that it outside of your 
control.  The best you can do is try to see if the duplicates were 
issued by your machine or came from somewhere else.
