The subject line of your post implies that you may have turned on 
Mailman's personalization to this list so that the return path is 
VERP'ed by Maiilman.

If that is the case then each subscriber will by definition be sent a 
unique message by Mailman for each posting distributed.

You would get a similar effect if, for instance, the MTA were 
generating VERP'ed messages from a single original message passed to it 
by Mailman but addressed to multiple addresses.

Could this be why you are seeing what you are seeing?
