Whenever my Exchange server (5.5 sp1 running on NT4.0 sp3) gets rebooted my
users get NDR notices from mail messages that were sent many days or even
weeks earlier. These NDR's are well beyond the notification schedule that we
have set. I think they must be cached somewhere and the reboot finally
clears that cache but I'm at a loss to explain why they are not delivered as
scheduled. What can I do to ensure that NDR's are being sent out when they
are supposed to?
