Greeting All:
We are running Exchange 2003 Enterprise on Windows 2003 server. We do have 4 different email domains coming to the Exchange server. But everything seems to be running OK. I checked and we do have a valid PTR and our mailserver is not listed on any black list.
The problem I am having periodically is that all of sudden, we get this 5.7.1 smtp...relaying denied message.
Here is the contents of the message:
Your message did not reach some or all of the intended recipients.

This message seems to be originating from my exchange server (ExchServer.mydomain.com is our Exchange server). This particular email was a reply to an email that John Doe had sent to one of our users. It also occurs when one of our user emails anybody at @company.com. Usually, within a day or two, it corrects itself and we can email each other fine. I have also experienced this with several other companies that we communicate with regularily. I did a nslookup from the Exhange server and it resolved it correctly to their mailserver IP.
I have been trying to find out why this temporary error occurs, but haven't found much. Do any of you have any suggestions? Thank you in advance!
