I guess this could also be called "aliases".

We are migrating our student email addresses from our EDU server to an OutlookLive email service hosted by Microsoft.  Students' email addresses will change from [log in to unmask] to [log in to unmask] We need a way to tell LISTSERV to recognize a subscriber when they start using their @masonlive.gmu.edu account.  

We are running LISTSERV 15.5 on Solaris 10.

thanks,
Mike
