i thought there was problem in sendmail. Apparently, i receive email as host goes down (critical).... i configured nagios to notify via email when there are WARNING in services.cfg but the problem is it not sending email as services goes WARNING. Below is some of the config of my services.cfg. BTW, im using Nagios 2.0
I tried to send email via terminal using mail command (e.g. mail email_add < test.txt -s "test" and i successfully receive the mail.
Is there a change in Nagios 2.0???
