There are mails on my account that were never read before the service was discontinued, and now I have no way of accessing them and removing the notification, and neither apparently does SE support.
This wouldn't be as much of a problem if it were only within the POL client, but the constant flashing back and forth over the in-game network meter is visually disruptive enough to make me not want to play.
What I want to know is if there is any sort of UI-altering addon that might be able to do something about this, or barring that, is it possible to delete or otherwise obscure the in-game mail notif icon or that entire section of the UI itself so it isn't visible any longer?
