Well, apologies for the email system being down for the last 24 hours. In short, I was hoping to move the flaming email server from one of my hosts to another and the move has been giving me grief.
So, after the fourth failure, I terminated the move and brought everything back online. Until I figure out why the grief on the move, it'll remain up...and I'll warn everyone next time.
Also, during the down time (about 24 hours), no data was lost and all incoming email was stored so nothing was dropped.
