using this feature with various usernames gives me no error. the problem is when i use the same username. for example :
firstname.lastname@example.org -> email@example.com
firstname.lastname@example.org -> email@example.com
firstname.lastname@example.org -> email@example.com
firstname.lastname@example.org -> email@example.com
user1 doesn’t work. it only sends emails to the first forwarding rule created. other users works ok.
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
