nagios not notifying by email

[Greg King]

The commands look correct. The one that works is using "mailx" and the one that fails is using "mail". I'd try mailx on the failing command, or verify that both work.

Hosts and services use different commands with different macros - make sure you are looking at the correct one (host-notify-by-email vs notify-by-email).

As for testing, I usually su - nagios; set env variables to the macro names, and copy/paste the commands into a shell until they work. Alternatively, use the check_dummy command with an error return code parameter. 

If notifications are happening you should see them in the notification log. If not, check parameters for notification on the host/service, timeframe, and contacts. 

Good luck!

Regards, Greg
