We get users that were married, and because of that they have a new name, and need a change of username / email adress.
Renaming a user is not a problem, but if i change the emailaddress, the user is not reachable on the old email adress anymore.

How can i change the primary emailadress to the new one, and save the old one for incoming mail from externals.
I can't find anything in the groupwise documentation!
