e-mail notifications not being sent

[Claudio Kuenzler]

Maybe you have to replace the mail program by something on your system,
e.g. /usr/bin/mailx.
That's always one of the first things I change in a new Nagios installation.
What OS are you using? Try to install the required programs (mail/mailx...)
if they can't be found in your system.
