If you run your own mail server, we would prefer that you manage your own messaging traffic. However, Eschelon does permit customer mail servers to smarthost mail to the internet through our servers. Please note that you MUST NOT use a NDR (Non-Delivery Response) configuration on your mail server. If you are having trouble with large queues of undeliverable mail, please read the guide below to shutting off NDR messages. If you send NDR mail through Eschelon, we may revoke your relay privileges. To learn more about NDR mail and how to disable it, please follow the link below. Or read the answer to the question “How do I disable NDR (Non-Delivery Response) messages on my Exchange or Exchange Small Business Server?” http://sysadmin.eschelon.com/faq/index.php?
