[Bug] mail not being delivered

None of my mail is in my inbox. For example, if I mail items from one alt to another all i see is the mail icon but when I open the mailbox there is nothing there. This is also the case when stuff is purchased from the AH, the icon lights up but there is nothing in the mail box.

I know others on my server are having the same issue. Not sure if it is everyone as some people in trade are claiming it works for them but entirely possible they are trolling.
