Smtp server

so reading the documentation i really don get where to put the enviroment variables, inn tht docker file? in the global enviroments inside the core plugin?, or im not finding the env file?

This just recently came up on Discord as well. There this screenshot was shared:

As such, in the docker-compose.yml file you should be able to add an environment section, along the lines of:

environment:
  - "KEY": "VALUE"
  - "OTHER_KEY": "OTHER_VALUE"

@martin.wacker elaborated there:

Add the environment variables to your docker-compose.yml (environment section if the server container).
The list of variables is here: Configuring email | AYON Docs

You may also use a .env file, to keep the actual values out of the docker-compose.yml, but you will still need to pass them to the container:
