Having problem with email notification setup
Posted: Thu Jan 11, 2018 11:44 am
Hi Folks,
I'm new to Nagios. I set up Nagios and want to set up email notification using Postfix.
I followed this article and set up Postfix. But when I try to send mail, I'm getting Undelivered Mail Returned to Sender and when I check Maildr, I get Held 2 messages in /home/myuser/Maildir. Requesting your help in this matter.

My commands.cfg :
Let me know if anything more is required and Thanks in advance for the help
