Mail Problems

After Deathwing and Ragnaros merged there are alot of problems with the ingame mails. A simple example is u have 2 guys with same names 1 is horde 1 is ally the horde get's to keep the name the ally does not log. Try send send a mail to that guy from the horde side will give u "Target is unfriendly" then i go to a ally char and try add that guy on friends list to see maybe he changed factions ofc i get the "cannot add different faction .....".

It happends since the characters on rag with name Y had the same name on dw.
So now one of them is blocked.
PS: its a big problem

Devs checked it, there are still a few names with it. Which one you found the problem?
