Below is the existing nagioscore system .mailrc configuration file. [nagios@nagioscore ~]$ vi .mailrc set -S smtp=mail...

The "myhostname" lines in main.cf file are commented out.

Re: set up email alerts notification in RHEL7

We have Nagios core currently running on RHEL 7, and would like to know how to setup email notification.

MS outlook is our company email server provider and mailrelay.int.company.com and port # already verified the communication between Nagios core host and mail-relay server is pingable.
