service:
  # For a Postfix running outside a container
  - type: "postfix"
    address: "127.0.0.1"
    port: 25


  # For an additional Postfix running outside a container
  - type: "postfix"
    instance: "NAME_ASSOCIATED_WITH_YOUR_ADDITIONAL_SERVICE"
    address: "127.0.0.1"
    port: 26


  # For a Postfix running in a Docker container
