 ### Create a docker-compose environment

+- Edit the files `.env` and `mailserver.env` to your liking:
   - `.env` contains the configuration for docker-compose
-  - `env-mailserver` contains the configuration for the mailserver container
+  - `mailserver.env` contains the configuration for the mailserver container
   - These files supports only simple `VAR=VAL` lines (see [Documentation](https://docs.docker.com/compose/env-file/)).
   - Don't quote your values.
   - Variable substitution is *not* supported (e.g. `OVERRIDE_HOSTNAME=$HOSTNAME.$DOMAINNAME`).
 
-**Note:**: Variables in `.env` are expanded in the `docker-compose.yml` file **only** and **not** in the container. The file `env-mailserver` serves this case where environment variables are used in the container.
