Ok, I will simplify the question.

Docker **container\_a** with a service configured to use Docker _network\_a_ needs to talk to **container\_b** (discourse) using the internal Docker network. With docker compose I would simply add _network\_a_ to the networks configured for the service in container\_b and set it as external.

I could reconfigure and rebuild my mail server but this is working configured as above for all my other docker container services I would rather have it working the same way for Discourse.
