Problems Forwarding-Only

using this feature with various usernames gives me no error. the problem is when i use the same username. for example : -> -> -> ->

user1 doesn’t work. it only sends emails to the first forwarding rule created. other users works ok.

any ideas?

user1@domain1 and user1@domain2 should be completely independent entries in the control panel.

So sending mail to user1@domain1 should only forward to user1@xdomain1
