We recently had an issue where the Email actions from alerts were firing ok, but they were failing overall (The server rejected the given recipient. The server responded: 550 5.7.1 Unable to relay.)
I am wondering if there is a way to setup an alert to capture if this happens again?
I've had a quick look and cant work out a way from the "I want to alert on:" field wen creating a new alert
Advice please?
