Hello -- in the last 15-30 minutes or so, all of a sudden, basically all of the mail I've received in a really long time has reappeared, unread, in all of my folders (Inbox, Junk, etc). I've gone from basically a clean inbox to having 9,000 unread messages in my inbox, all of which I'd previously deleted.

Anyone else see this? Or know why it may have happened?
