This is good. Nagios is trying to execute the notify-service-by-email  
command.

... and nagios believes it was successful

as the nagios user? (just covering the base)...

How about eliminating /usr/bin/mail entirely and dumping text to a  
file in /tmp?

	command_line echo `date` ' - I notified!' >> /tmp/notif.log

That's interesting and my money is on it being some problem related  
to /usr/bin/mail. You might try capturing the output of /usr/bin/mail  
by redirecting to a log file --

command_line    echo "testing" | /usr/bin/mail -s "** TEST SUBJECT **" my at email.address 
  >>/tmp/mail.err 2>&1
