Hi,

The SMTP details are written in `container/app.yml`.

You must then restart the container: `./launcher restart app`

If you change the smtp settings you need to destroy and start the container.

```
 ./launcher destroy app;./launcher start aop

```

Restarting does not update the environment variables passed to the container
