Players are now able to mail account-bound items to other characters that reside on a different realm on the same account. To send cross-realm mail: enter the character's name, followed by a hyphen "-", followed by the realm name. Note that cross-realm mail can only send account-bound items, not other items or gold.
Additional information and testing discussion for this cross-realm mail can be found in this thread on the PTR Discussion forum.
