Hello,
I haven’t changed anything, and now email alerts have stopped working. The only changes are the nightly upgrades, and this was working 2-3 weeks ago.
If I go to Settings > Global Settings > Alerting Settings > Email transport > Test transport, I get the following message:
Test to mail failed
**Invalid address: (addAnAddress to): 0**
I tried adding a new alert transport in Alerts > Alert Transports, but I get the same message. sysContact is set on the devices.
