If you "su" to the Nagios user, and just run "mail" - does it yield 
anything, or "command not found"?

The error seems to be (as someone previously said) it's piping your 
notification text to " -s "Host DOWN..."" which isn't a valid command.
You need to change your notification command to pipe the result to "mail 
-s ...." instead of " -s ..."

You may also need to try "sendmail" (I don't use sendmail so I don't 
know if "mail" is part of it or not.)
