NRPE allows you to connect to the system being monitored, and execute
any command on the local system, returning the result to the Nagios
server. In your case, you could either check for TCP connectivity on
127.0.0.1:10024 or use the check_procs plugin to see if the process is
running -- or both.
If firewalls etc prevent you configuring the Monitoring server
connecting to the Mail Server to initiate NRPE checks, then you can
use NSCA which is basically the same thing, except the machine being
monitored is responsible for checking the status, and sending
notifications to the monitoring server ("passive checks").
