I have removed the First Server from the First Administrative Group according to the microsoft white papers. http://support.microsoft.com/kb/822931
I have moved all of the users to the new sever weeks before removing the first server. It has been set as the Master after moving all of the users several weeks ago.
I show quite a few queued messages refering to the old server, most of them are Delivery Status Notifications from Post Master.
Two items look to be valid messages.
Not sure if this issue will resolve itself or what needs to be done.
