One of nice Opensource monitoring tool, Zenoss. Got error message to send admin with alrets or report. "Test failed: – [Errno 111] Connection refused"

Here is simple step to fix it

1. Assess Zenoss console as admin and install postfix server

2. Reboot the system and it should be good to go with default setting of Postfix server. If you want, check configuration file at /etc/postfix/main.cf
