I run about 200 lists, so get this complaint fairly regularly.  In 
virtually every case, or every case it turns out to be user error -- 
Mailman just doesn't send out duplicate posts, it seems to me.  People 
may have subscribed under two different addresses, or in one case the 
user had a mail filter in place that was bad, and directed messages to 
two different places.

Unsubscribe their address, and if they still get messages, have them 
forward to you with headers, so you can see what is going on at their end.
