Bad Email Bug

I have submitted and in game Bug Report for this. I Use the surname to differentiate between my horde and Alliance Characters. If I have two Characters of the same First Name but Different Surnames and I attempt to Mail this character from an alt then I receive the message unfriendly Target. Ite seems the mail system is unable to tell the difference in names. Please address this bug before the game goes live.

Thanks

Same issue found. Additionally, if you have a THIRD toon with a completely different name, you can ONLY mail the alt that was created first with that shared first name. No matter how many times you select the later one, the mail always goes to the oldest character with that same first name.
