You will need to use the virtusertable (as Rodolfo mentions) to have 
usernames that are different per domain.  It is likely that the 
following is true in your case:

user at mail.xxx.net is the same as user at mail.xxx.org

If that is *NOT* true, then you need to use virtusertable functionality 
to make the proper distinction.
