WotLK Character trade and C.O.D mails

[angrylol]

Hey,
What happens to C.O.D mails in my mailbox if I put the character up for trade?
Can I ask some sucker to send me 50 stacks of primos and just delete them from game? Can't remember, but I think mails were deleted, or are they returned?

Mail is returned if COD and deleted if it doesn't contain any items.
