I am guessing that not only does sendmail have to be installed, but the Nagios server must also act as a mail server.  Can someone please guide me in arranging this setup correctly as I am stuck and need to get alert notifications setup correctly soon.

Sendmail as activated default by RHEL will listen on the loopback
address only and send out email to any address you please to send it.

The ony thing you might want to add is a smarthost to send it all to the
central SMTP server.

Nothing too complicated. The thing you do not know yourself can be found
in a matter of seconds with a decent search engine.

But configuring sendmail is not a Nagios job.
