You don't have any SMTP server in your environment? If you have your own email server on site, you should consult your sysadmin to see what you should be using for an SMTP server. Configuring postfix is going to be out of the scope of this forum. I can link you to this article which is likely applicable. https://www.digitalocean.com/community/ ... untu-14-04

i don't understand why one of them is working and another one isnt. they both are using mail and both email address are in same domain. and no filters or restrictions on theme.

What is the output of the following command?

Code: Select all

grep inet_protocols /etc/postfix/main.cf

Posted: **Tue Oct 27, 2015 11:52 am**

Code: Select all

ubuntu@nagios-2015:~$ grep inet_protocols /etc/postfix/main.cf
inet_protocols = all
ubuntu@nagios-2015:~$

Can you change that to inet_protocols = ipv4, restart postfix, and try your mails again?

Posted: **Tue Oct 27, 2015 2:42 pm**

i did that change on postfix and restarted postfix and nagios.
still not working.

Posted: **Tue Oct 27, 2015 2:43 pm**

Can you post the mail log of it not working since making that change?

Those logs tell me that it is working, but you're sending to the same machine it is originating from...? I'm a little confused. Did you use the command to try to send the mail, or wait for Nagios to do it on its own?

i am waiting for nagios to do it.
it is sending for warning email but not to critical mail.
That is the only problem.
