Well I am kinda backed into a corner and am running out of time to handle
a problem that was brought to my attention today.  In 2 weeks, we are
doing a mass migration of our email services we do on a campus level to a
new machine.  As part of the migration, we are creating the possibility
(and recommending this) of using a shortened version of our address
scheme.  Right now, 99% of our mail is addressed as [log in to unmask]
After the conversion to the new mail server and the addition of webmail
facility, we have a large number of users that will be starting to resolve
(or have reply-to: set) to [log in to unmask]

Well as was pointed out to me, there is going to be a major issue with
lists that the listowner address will no longer be "correct" if the owner
doesn't do some pre-emptive changes to the header configuration.  In
addition, users who don't listen to our mass spams on campus concerning
the migration may have issues if the list is set to a form of subscriber
only or moderated lists.

Has anyone dealt with this type of massive overhaul and built a way to
parse the list headers and add the new way of addressing for all
listowner?  If not, does anyone have suggestions of how best to handle
this situation.

Help!
