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

Note: If your postgrey unix socket is anywhere other than
/var/spool/postfix/postgrey/socket you will either need to modify the source or add the -s argument to specify where it can be found.

2) Copy check_postgrey.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_postgrey.pl
or
chmod +x /usr/lib64/nagios/plugins/check_postgrey.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: Postgrey mail policy
check_command check_postgrey!3!9
}
