I've been thinking about this and I want to put all system users in the 
database using the provided tools from postfixadmin and then sync the 
mail using imapsync.
In that case domain admins can handle their own mailboxes using 
postfixadmin.
In that case I have all users as virtual users, but they have to be able 
to login with only their username.
That means new users should login by using their complete emailaddress 
and old users as username or emailaddress.
so:
old user: info at domain1.com user: info can login as info or info at domain1.com
old user: info at domain2.com user: info.ltd can login as info.ltd or 
info at domain2.com
new user: info at domain3.com can login only as info at domain3.com
if the new user tries to login as info he gets a password failure
Is this possible an correct ?
