How to not bind HTTP and HTTPS ports at all?

lriley06

I want to use mailcow with an nginx container as a reverse proxy and have added the nginx-mailcow container to my custom docker network so it can be accessed from the reverse proxy. How can I ensure that the nginx-mailcow does not have any port bindings added to it?

After a bit of digging, it seems that the only way to do this is manually editing the docker-compose file and deleting the ports section from the nginx-mailcow service

Hm, I think a better approach is actually described in the docs:

Sorry for bumping old thread, but just noticed your reply here so thought I’d just respond the sake of anyone else with the same issue! I seem to remember that mailcow refuses to start if the port bindings are just empty, so the only way to resolve this is indeed manually editing the docker compose file.
