Fixed Bug 8151

map server will no longer complain when it receives mail data for a character that is no longer online (its a pretty silly thing, consider you login, it requests mail data, you logout while it still hasn't arrived -> it annoys you with a warning when it arrives)
Special Thanks to Frost!
