We are using two exchange relays to send out alerts within Nimbus. We have them set within the Email gateway probe.
Primary relay is: extrelay.abc.com (based in US)
Secondary relay is: ukextrelay.abc.com (based in UK)
Currently, we have our Primary relay server down and we were hoping that the secondary relay would pick up the task and start sending alerts.
However it’s not happening. I am not sure why. I have seen this in the past but didn’t get chance to pick up to the logs.
Upgrading to emailgtw version 2.50 fixed the issue with a fallback smtp server not being able to take over when the primary server failed.
