Because it wasn't sent. Either /usr/bin/printf doesn't exist or /bin/mail doesn't exist. Make sure the packages that provide them for your system are installed.

Was nagios compiled on this same box? Did you change this command in any way after install? Nagios is pretty good about detecting these kinds of things during the ./configure phase and/or your package maintainer should have detected it.
