[Mailman-Users] not recognized

Dear List:

I have the strangest thing happen EVERYTIME I add anyone new, to any list. I
receive two messages. The first is a notice indicating the address was
successfully added to said list, a la:


From: mailman-bounces at fyrenice.com
Date: Thu, 27 Mar 2008 15:26:28 -0600
To: sanchiro-patients-owner at fyrenice.com
Subject: sanchiro-patients subscription notification
Firstname Lastname <firstandlastnames at msn.com> has been successfully
subscribed to sanchiro-patients.


The second looks like the following:


From: mailman-bounces at fyrenice.com
Date: Thu, 27 Mar 2008 15:26:36 -0600
To: sanchiro-patients-owner at fyrenice.com
Subject: Uncaught bounce notification

The attached message was received as a bounce, but either the bounce
format was not recognized, or no member addresses could be extracted
from it. This mailing list has been configured to send all
unrecognized bounce messages to the list administrator(s).

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed permanently:

* anynamegoeshere-owner at msn.com

I'd like to know how to reconfigure my installation so that I do not keep
generating this error, with the -owner@ on every newly added address.
