I tried 188.8.131.52 and a DNS server closer to home, 184.108.40.206, but neither one worked - I still didn't get the test e-mail.This tells me that hosts inside the firewall are not allowed to do DNS lookups to external hosts. As the switch is inside the firewall, then using an external DNS server will not work. Any other ideas?

Summary: The problem was caused by an invalid MX record in our DNS server.Secondly, there should have been a log that recorded the failed attempts to send e-mails. I looked everywhere but I didn’t find one. Had this log been available we would have been able to resolve this issue a lot quicker.

The root cause is that the Fabric OS does not allow for a complete sendmail configuration. The smart_relay is an important sendmail option and there is no provided interface to set it. .../Ed
