The inet_interfaces parameter is one of the few that requires a restart rather than a reload when it is changed in order to change the listener sockets associated with master.cf inet services. http://www.postfix.org/postconf.5.html#inet_interfaces So that would be: # postfix stop # postfix start A less invasive change is: # postconf -e "master_service_disable = inet" # postfix reload Because this disables the inet services, rather than attempts to change the underlying sockets, it does not require a restart, and the queue manager and outbound deliveries continue without interruption. -- Viktor.
