Description of problem:
=======================
email notifications are not sent from nagios server which is installed on one of the RHGS nodes
Even though all the related stpes are completed to configure mail notifications on the nagios server, mails are not received.

Troubleshoot:
============

when the same email command was executed from the command line below error was seen,
[root@casino-vm1 gluster]# /usr/bin/printf "%b" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress: $HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | /bin/mail -s "** $NOTIFICATIONTYPE$ Host Alert: $HOSTNAME$ is $HOSTSTATE$ **" $CONTACTEMAIL$
[root@casino-vm1 gluster]# send-mail: fatal: parameter inet_interfaces: no local interface found for ::1

After googling it was found that this was an issue with postfix service.

after disabling IPv6 on the node emails were received.

Note: Similar kind of issue was seen on RHEL7.2 RHGS3.1.2 node but after using postfix and starting postfix service resolved the issue.

2.configure nagios and configure email notification
3. send notification from one of the services on nagios UI

Since this is an issue with the mail service used, closing it not a bug in this component. 
Before configuring email notifications on nagios server, user is expected to test the mail configuration. The KB article referenced in Comment 1 can be used to fix issue with postfix
