Is that actual character on your friends list? Not just one of their characters, but the one by that name? If so, it should show up as a suggested name to mail to. (I've switched kins and had friends switch kins on me, and I've never had a problem - if they're on the friends list, they still show up. If your friends don't, it might be a bug).
