Earlier today we had to flush the queues on ExchangeDefender outbound server due to the large number of corrupt queue files sent by one of our customers malfunctioning servers. If your messages were not delivered during the window between 5am – 7 am central (GMT -6) please resend them.

The problem has been solved temporarily, but we will be holding an urgent maintenance window this Wednesday, 5/14, to address the core of the problem.

P.S. Significant number of servers were backlogged during this process. That mail has been processed without issue.
