Go to the very bottom of the screen and there is color bar and a quantity showing how many messages you have stored in your inbox and sent items. You need to periodically select a bunch of messages and delete them.
There is another thread reporting problems with the Forum software. No email notifications of new posts and the Report Post button not working. Perhaps symptoms of a wider issue? Perhaps a recent software upgrade at the vBulletin end?
Maybe it's time for a forum server reboot. In the Auran olden days, this was done often because posts wouldn't appear, and notifications wouldn't show up in mailboxes.
