So I recently created a character in a realm (Ector-36) different from my original realm (Bors-26). But it seems that the mailbox is still bound to the original realm. So when I open the mailbox in Ector-36 I can only see my messages from Bors-26. People seem to be able to send me private messages, and I get the little red number on top of the envelope on the main screen, but when I open it, it again goes to my mailbox from Bors-26. A couple of other people in my guild seem to be having the same issue.

Sorry, the title should have been MAILBOX in a new realm. My apologies.
