I also need you guys to verify that with the Postfix master running
as PID=1, "docker stop" will no longer leave the master daemon
running until Docker times out and forcibly terminates everything.
By default, "docker stop" should send signal SIGTERM (signal 15) which
is what Postfix expects, but it is good to verify.
