[Mailman-Users] Duplicate Messages

[David Andrews]

My Mailman system sends out duplicate (two copies) of some 
administrative-type messages.  There are two password reminder 
messages sent out each month, two copies of the once-a-day message 
that announces pending messages in a list, and two messages each 
morning at 8:00 a.m. from the list mailman.  There isn't such a list 
where the links work, can be edited etc.  Presume it is the template 
for other lists, or some such thing.

What causes these behaviors and how do I fix them?  Thanks in advance.

Dave
