You need to look at the Internet Received: headers on those messages 
to determine where the resending is actually happening.  I'm not a 
betting man but I'd lay odds that you'll find that LISTSERV isn't 
resending anything, and it's actually a broken mail server somewhere 
in the downstream (from LISTSERV) path that's doing it.
