Opmanager is not sending out notifications when an alert is triggered. I looked at the notifications log and I found why it isn't.
"Could not connect to SMTP host: localhost"
For some reason Opmanager is trying to use localhost to send out notifications even though it is configured to use our mail server as it's smtp host under Admin - Mail Server Settings. I went back and reconfigured the mail server setting but it is still trying to use localhost. Any ideas on how to fix this.
