Description
Solution
Issue:
SMTP Connector not working post configuration settings. There may be a case where the connector is not showing available during the health check after all the necessary configurations made.
Root Cause:
Postfix service is not running. This service has to be up and running whenever we need SMTP connector to work.
ssh to the box where CyOPs is hosted and
Use “systemctl status postfix” to check whether the service is up.

Solution
Fix:
Bring up the postfix service by firing the below command when you ssh to the box where the CyOPs running.
“systemctl start postfix”
Later use “systemctl status postfix” to check whether the service is up.
