I have a new Microsoft SBS Server - This is set up for a small engineering firm. Occasionally, almost daily, I have trouble delivering mail to a couple of domains. I googled the message "Delivery is delayed to the following recipients or groups..."
Solutions seem to point to IP 6, or DNS issues, I found this site, and have decided to post my own question.
To get the mail delivered, I could restart the server. This obviously is not a solution. I found a script that stops and starts all the Exchange services, but that was not the solution.
I finally stopped the DNS Service, and restarted. Then in the Exchange Queue Viewer, I selected Retry, and the mail was delivered.
Has anyone seen this behaviour, and is there a solution I could implement on a more permanent basis.
Thanks
