Sorry, I was wrong about there being mail in there. Its been a couple years since I opened it. I do have mail in mine though, but its mostly from users who responded to the outage alerts I sent from the besadmin account and some other random stuff. I should have looked closer to see that it wasn't actually the user mail.
Although, I swear when I looked in that mailbox when we were running 3.6, there actually was BB users mail in there... I could have been smokin that day though
