When Postfix is running in a Docker container, it's most useful to use
the built-in Docker logging (as with Systemd). Setting
`--docker.enable` allows that.
The log source is using `client.NewEnvClient`, which reads environment
variables to determine which Docker to connect to, and how TLS is
handled.
