I did setup Stalwart like this:

~$ mkdir /home/myuser/docker/stalwart

~$ nano /home/myuser/docker/stalwart/docker-compose.yaml
services:

  stalwart:
    image: stalwartlabs/stalwart:latest
    container_name: stalwart
    restart: unless-stopped
    ports:
      - 8443:443
      - 8008:8080
      - 25:25
      - 587:587
      - 465:465
      - 143:143
      - 993:993
      - 4190:4190
      - 110:110
      - 995:995
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /etc/localtime:/etc/localtime:ro
      - stalwart-etc:/etc/stalwart
      - stalwart-data:/var/lib/stalwart
    environment:
      - STALWART_PUBLIC_URL=stalwart.mysubdomain.mydomain.net
    networks:
      zoraxynet:

volumes:
  stalwart-etc:
  stalwart-data:

networks:
  zoraxynet:
    external: true

But I get error 521 not reachable with my url.
Calling it by myip:8008 it works.

All my other docker stuff is working with the Zoraxy reverse proxy.

Also I see:

>Window.fetch: http://myip:8008Stalwart.mysubdomain.mydomain.net/jmap/ is not a valid URL.

when I login to Stalwart.
