We are running Exchange 2003 on SBS R2 and Outlook 2003. Periodically we get
NDR's on internal messages that say :
"The message could not be delivered because the recipient's destination
email system is unknown or invalid. Please check the address and try again,
or contact your system administrator to verify connectivity to the email
system of the recipient.
<ourdomain.com #5.1.2>"
This seems to be very intermitent and, of course, usually happens to our CEO
who finds it to be a big deal.
In the past I have manually run the Recipient Update Service which seemed to
correct the issue for a while. The only changes to the server was a restart
a couple days ago. I have also searched for the 5.1.2 error but did not find
anything that seems applicable.
Any help from the pros would be greatly appreciated! Thanks in advance.
