This is a host notification, not a service notification so I can't  
show you *exactly* what to do but I'll give you the example for the  
above and let you extrapolate --

         command_line    /usr/bin/printf "Subject: [Nagios]  
$SERVICESTATE$: $SERVICEDESC$ $HOSTNAME$\nFrom: nagios@$HOSTNAME 
$.mascorp.com\n\n ***** Nagios *****\n\nNotification Type:  
$NOTIFICATIONTYPE$\nHost: $HOSTNAME$\nState: $HOSTSTATE$\nAddress:  
$HOSTADDRESS$\nInfo: $HOSTOUTPUT$\n\nDate/Time: $LONGDATETIME$\n" | / 
usr/sbin/exim "[Nagios] $HOSTSTATE$ $HOSTOUTPUT$" $CONTACTEMAIL$
         }

Note the change after '|/usr/sbin/exim'. That's where the Subject is  
specified. For a service notification, you'd use $SERVICE*$ instead of  
$HOST*$. You may not need $HOSTSTATE$ depending on if the plugin  
includes the CRITICAL text already.
