Mailbox not working

Today i am not able to open the mailbox. Is anyone else having this problem?
I am not running addons and tried relogging but i can not interact with the mailbox at all.

Edit: it seems to only be on one character. The mailbox that did not function for her is in Dolanaar. I will go and try more of them.

Edit 2: There are more people with this problem, and more mailboxes that do not work today. I found the one in Darnassus worked for me. Someone in SW also had one that did not work.

Same happened to me in Dolanaar today. Seems mailbox is bugged there.
