mail notifications

This is not really a possibility due to my scenario.  The nagios box is not
on the Internet, and therefore, does not have an Internet DNS MX record.  I
cannot relay off my corporate Email.  This is also not desirable, as I
would like to be able to monitor the corporate Email server and cannot
receive notifications via my cell phone Email account to which I am sending
if the Email server would be down.

What I can do is send an Email from a client on the nagios box to my isp's
smtp server as nagios at tds.net (my isp is tds).  This Email is properly
routed to my cell phone Email address.  I'm not sure of a better way to
handle this at this point.

Uh...

Try forcing your SMTP to send as "nagios at address"  Where address is
your server's *real* IP address, or your server's DNS.

nagios at localhost is probably not a good idea.

localhost means "this computer" so maybe your ISP's mail server is
thinking "This didn't come from me!!" and throwing it away.

  Just an idea.
