Hi Clouseau,
if you don't have either Policyd or Cluebringer running, please remove 'check_policy_service inet:127.0.0.1:10031' in Postfix config file /etc/postfix/main.cf first, then restart Postfix, so that your mail server can continue working.
I will public wiki tutorial for installing Cluebringer later.
Tnx I allready did it 
Great!
