To install:

1) add the following to your local-commands file (e.g.
/etc/nagios/conf.d/local-commands.cfg)

# 'check_postgrey' command definition
define command{
command_name check_milter
command_line $USER1$/check_milter.pl -w $ARG1$ -c $ARG2$
}

Note: If your milter server is anywhere other than localhost:8891 you will either need to modify the source or add the -p and/or -h arguments to specify where it can be contacted.

2) Copy check_milter.pl to where your NAGIOS plugins are installed on the host that will be checked and set appropriate access permissions: e.g.
cp check_postgrey.pl /usr/lib64/nagios/plugins/
or
cp check_postgrey.pl /usr/lib/nagios/plugins/

and
chmod +x /usr/lib64/nagios/plugins/check_milter.pl
or
chmod +x /usr/lib64/nagios/plugins/check_milter.pl

3) Add the following (adjust parameters to your own requirements) to each host specification that is to be checked:

define service{
use local-service
host_name
service_description Mail: filter policy server
check_command check_milter!3!9
}
