Perhaps the problem was that master.cf contains a service endpoint (in the first column) that specifies a hostname instead of an IP address? Or main.cf:inet_interfaces has a hostname instead of IP address? Either of these could introduce a start-up dependency on DNS, if the name is not found in /etc/hosts. Wietse
