I run Nagios Core 3.2.3 and running postfix as mt mta agent in Ubuntu 10.4.
I have setup nagios alerts to send to me and to send to our ticketing system which is email@example.com.
My ticketing system has a auto responder which responds to end users so with that basically whenever Nagios sends alerts to firstname.lastname@example.org it auto responds to nagios - unfortunately it fails:
Your message could not be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can delete your own text from the attached returned message.
The mail system
email@example.com: Host or domain name not found. Name service error for name=monitor22.csaa.local type=A: Host not found
My question is, how can I make Nagios/Postfix receive emails within?
Pls kindly advise mates.
