Hi, We've been running Exchange Server 2003 for about 1.5 years with no problems. Then recently we've been having incoming emails bounced intermittently with the following message (i've changed the addresses, obviously):
---------- Forwarded message ----------
From: Mail Delivery Subsystem <firstname.lastname@example.org>
Date: Jul 20, 2006 11:36 PM
Subject: Delivery Status Notification (Failure)
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
It only happens once in a while. and if the person re-sends the email a couple minutes later it will usually go through in 1 or 2 more tries.
I'm not very familiar with managing exchange server. is there a place i can look to see what happened (like a log file)? any idea why this is happening?
