Hi, i have little problem to set-up correctly my yml file for traefik mailcow.
Can somebody help me please ?

I used this path for traefik: /home/archmatt/traefik
inside traefik folder is:

docker-compose.yml
data (Folder)
(Inside data folder) | acme.json
(Inside data folder) | config.yml
(Inside data folder) | traefik.yml

I am using wildcards (CLOUDFLARE), and create network called: proxy

Portainer path is: /home/archmatt/portainer
inside portainer folder is:

docker-compose.yml

Already set-up traefik, portainer, also redirect to another server works fine.
in portainer docker-compose.yml i just add labels:

labels:
      - "traefik.enable=true"
      - "traefik.http.routers.portainer.entrypoints=http"
      - "traefik.http.routers.portainer.rule=Host(`portainer.yourdomain.com`)"
      - "traefik.http.middlewares.portainer-https-redirect.redirectscheme.scheme=https"
      - "traefik.http.routers.portainer.middlewares=portainer-https-redirect"
      - "traefik.http.routers.portainer-secure.entrypoints=https"
      - "traefik.http.routers.portainer-secure.rule=Host(`portainer.yourdomain.com`)"
      - "traefik.http.routers.portainer-secure.tls=true"
      - "traefik.http.routers.portainer-secure.service=portainer"
      - "traefik.http.services.portainer.loadbalancer.server.port=9000"
      - "traefik.docker.network=proxy"

BUT: as documentation say in mailcow are stored /opt/mailcow-dockerized/
so i create it already, and edit mailcow.conf:

HTTP_PORT=10080
HTTP_BIND=127.0.0.1

HTTPS_PORT=10443
HTTPS_BIND=127.0.0.1

SKIP_LETS_ENCRYPT=y

then i created docker-compose.override.yml as it said in documentation:

version: '2.1'

services:
    nginx-mailcow:
      networks:
        # Add Traefik's network
        - proxy
      labels:
        - traefik.enable=true
        # Creates a router called "moo" for the container, and sets up a rule to link the container to certain rule,
        #   in this case, a Host rule with our MAILCOW_HOSTNAME var.
        - traefik.http.routers.moo.rule=Host(`${MAILCOW_HOSTNAME}`)
        # Enables tls over the router we created before.
        - traefik.http.routers.moo.tls=true
        # Specifies which kind of cert resolver we'll use, in this case le (Lets Encrypt).
        - traefik.http.routers.moo.tls.certresolver=le
        # Creates a service called "moo" for the container, and specifies which internal port of the container
        #   should traefik route the incoming data to.
        - traefik.http.services.moo.loadbalancer.server.port=${HTTP_PORT}
        # Specifies which entrypoint (external port) should traefik listen to, for this container.
        #   websecure being port 443, check the traefik.toml file liked above.
        - traefik.http.routers.moo.entrypoints=websecure
        # Make sure traefik uses the web network, not the mailcowdockerized_mailcow-network
        - traefik.docker.network=proxy

    certdumper:
        image: humenius/traefik-certs-dumper
    command: --restart-containers ${COMPOSE_PROJECT_NAME}-postfix-mailcow-1,${COMPOSE_PROJECT_NAME}-nginx-mailcow-1,${COMPOSE_PROJECT_NAME}-dovecot-mailcow-1
        network_mode: none
        volumes:
          # Mount the volume which contains Traefik's `acme.json' file
          #   Configure the external name in the volume definition
          - /home/archmatt/traefik/data/acme.json:/traefik:ro
          # Mount mailcow's SSL folder
          - ./data/assets/ssl/:/output:rw
          # Mount docker socket to restart containers
          - /var/run/docker.sock:/var/run/docker.sock:ro
        restart: always
        environment:
          # only change this, if you're using another domain for mailcow's web frontend compared to the standard config
          - DOMAIN=${MAILCOW_HOSTNAME}

networks:
  web:
    external: true
    # Name of the external network
    name: proxy

volumes:
  acme:
    external: true
    # Name of the external docker volume which contains Traefik's `acme.json' file
    name: proxy

and then when i put command for docker:

sudo docker compose up -d --force-recreate
#output:
yaml: line 29: mapping values are not allowed in this context

so how to fix it or should i change somehow config for override ?
