postgrey running but shows up DOWN

[djtech]

System is running fine, but under server status it shows that postgrey service is down. When I checked with "/etc/init.d/postgrey start" it says that postfix greylisting is already running and a Pid_file already exists.

I also checked /etc/postfix/main.cf and it shows "check_policy_service inet:127.0.0.1:6000," as an smtp_recipient_restriction and it is not commented out. So, if the service is running and the config file is ok, why is the status DOWN? What am I missing?
