Previously, Checkmk agent used the data from /proc to determine if Postfix instance is running. Since docker containers don't have permissions to read /proc, the agent always reported the Postfix instance as 'not running'.
This resulted in CRIT 'Postfix status' service even if Postfix instance was running correctly.
