I am hoping to get some more information regarding the above error message. I have a client who is having trouble sending emails to my Exchange 2003 server where we host the mail for company.com.
The MS Knowledge Base gives you this explanation:
But there really isn't an explanation (or more imporantly a solution or workaround) to the above error message.
What does this message mean that 'the remote domain has prohibited the sending domain from relaying'? Why is relaying even involved, when it has reached it's final destination?
Some light on this for me would be appreciated.
