# To build the image:
# sudo docker.io build -t box .

# Run your container the first time with an interactive console so you can
# create your first mail account.
# sudo docker.io run -i -t box

# Then run it in the background and expose all of the ports so that the *host* acts as a Mail-in-a-Box:
# (the SSH port is only available locally, but other ports are exposed publicly and must be available
# otherwise the container won't start)
# sudo docker.io run -d -p 22 -p 25:25 -p 53:53/udp -p 443:443 -p 587:587 -p 993:993 box
