i would try the suggestion outlined here - https://www.freelock.com/kb/postfix-relayhost

if that doesn't work, troubleshoot your way through the notification.
1. get it working over the command line, without Nagios
2. then set it up in Nagios once you confirm it's working

it could be a variety of different things ranging from your SMTP settings / where mail is installed - without any direct info it's hard to say.

did you configure the mail server .

you will be finding it in below path check this once

vi /etc/mail.rc

at the bottom you have to configure the mail server ip port as below

set smtp=smtp://Mail Server IP
set from=" mail id" --from which you want to receive
set smtp-auth=login
set smtp-auth-username=username --- smtp mail username
set smtp-auth-password=password --- smtp mail password

Did the above suggestions help?

To tacolover101's point, try to determine where the problem is by trying to send an email from the command line. For example:

Hey its working here problem with my postfix

Thanks
