I have nagios set up and configured the way I want, but it refuses to notify the email address I send it when our test server goes down. It sees it as down in the web interface, but when it tries to email, I get this error in Konsole:
temporary mail file: permission denied
I am using /bin/mail for my command-based email client. I can successfully email a test message using
/usr/bin/printf "test" | /bin/mail "test" "email@example.com"
/bin/mail only fails when the command is called from nagios.
I gave the user "nagios" full rw rights to everything in /usr/local/nagios, /usr/bin/mail, and /var/mail. "nagios" is a member of the apache, mail, nagios, and even root groups. My mail log didn't seem to have anything about that, but I can post it if it would make it easier for you to help me out.
System information: PCLinuxOS, kernel 22.214.171.124.
Thanks for the help!
