Some emails are returned
Posted on 2010-08-17
How can I troubleshoot some issues with my exchange server when some emails are returned at random. It does not happen on a daily basis but important emails to some users are been returned. The email address is correct.
Today's email error is as follow:
This is an automatically generated Delivery Status Notification.
Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server.
firstname.lastname@example.org (removed on purpose)
Reporting-MTA: dns;servername.net (actual server name changed) Final-Recipient: rfc822;email@example.com Action: failed Status: 4.4.7 X-Display-Name: firstname.lastname@example.org
Any help is greatly appreciated.
