When trying to send out an email to a user at @xyz.com I am getting a "Delivery Final Failure Notice" bounce back that contains: Can not deliver the message you sent. Will not retry. Sender: <someone@here.com> The following addresses had delivery problems <abc@xyz.com> : Reply from []: <<< Relay domain does not exist. It is only a problem with this address as all other external mail is working fine. I have checked the both our mail servers and DNS records however everything looks normal, nothing has been changed on them for quite some time. HELP!

If you're connecting to the machine found in the MX record for the domain then you'll have to contact the admin at the other domain to find out what their problem is. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP
