[Mailman-Users] odd message to owner when adding addresses to list

[Con Wieland]

when I add an a new subscriber via the admin Mass Subscriptions I receive the following bounce


From: MAILER-DAEMON at mta3.service.uci.edu
Date: December 15, 2011 10:01:50 AM PST
To: pal-allprocessors-bounces at department-lists.uci.edu
Subject: Returned mail - nameserver error report


--------Message not delivered to the following addresses:

 cwieland-owner at uci.edu 

--------Error Detail (phquery V3.0):

---- cwieland-owner at uci.edu 
    Does not exist, and no people with that alias(UCInetID) are at UCI.

Please contact Postmaster at uci.edu if you have any questions.

example -  I add cwieland at uci.edu and it sends the confirmation to cwieland-owner at uci.edu 

any ideas?
