Mailcow + Traefik - Multiple Domains

[Blaccii]

Hi,
The stuff is all Working, i just want to add an second Domain.
The .yml looks like that:
docker-compose.override.yml

networks:
  proxy:
    name: proxy
    external: true

services:
  certdumper:
    image: ghcr.io/kereis/traefik-certs-dumper:latest
    restart: unless-stopped
    network_mode: none
    command: --restart-containers mailcowdockerized-postfix-mailcow-1,mailcowdockerized-dovecot-mailcow-1
    volumes:
      # Kommentiere den Pfad aus je nach dem welche Anleitung du verwendet hast!
      # Für Anleitung: "Traefik V3 Installation, Konfiguration und CrowdSec-Security"
      #
      # - /opt/containers/traefik-crowdsec-stack/data/traefik/certs:/traefik:ro
      #
      # Für Anleitung: "Traefik v2 + 3 – Reverse-Proxy mit CrowdSec im Stack einrichten"
      # - /opt/containers/traefik-crowdsec-stack/traefik:/traefik:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./data/assets/ssl:/output:rw
    environment:
      DOMAIN: ${MAILCOW_HOSTNAME}
      ACME_FILE_PATH: "/traefik/tls_letsencrypt.json"
    healthcheck:
      test: ["CMD", "/usr/bin/healthcheck"]
      interval: 30s
      timeout: 10s
      retries: 5

  nginx-mailcow:
    networks:
      proxy:
    labels:
      traefik.docker.network: proxy
      traefik.enable: "true"
      traefik.http.services.nginx-mailcow.loadbalancer.server.port: "80"
      traefik.http.routers.nginx-mailcow-euredomain_de-secure.entrypoints: websecure
      traefik.http.routers.nginx-mailcow-euredomain_de-secure.rule: "Host(`mail.euredomain.de`) || Host(`autodiscover.euredomain.de`) || Host(`autoconfig.euredomain.de`) || Host(`mta-sts.euredomain.de`) || Host(`imap.euredomain.de`) || Host(`pop3.euredomain.de`) || Host(`smtp.euredomain.de`)"
      traefik.http.routers.nginx-mailcow-euredomain_de-secure.service: nginx-mailcow
      traefik.http.routers.nginx-mailcow-euredomain_de-secure.tls: "true"
      traefik.http.routers.nginx-mailcow-euredomain_de-secure.tls.certresolver: tls_resolver
      traefik.http.routers.nginx-mailcow-euredomain_de-unsecure.entrypoints: web
      traefik.http.routers.nginx-mailcow-euredomain_de-unsecure.rule: "Host(`mail.euredomain.de`) || Host(`autodiscover.euredomain.de`) || Host(`autoconfig.euredomain.de`) || Host(`mta-sts.euredomain.de`) || Host(`imap.euredomain.de`) || Host(`pop3.euredomain.de`) || Host(`smtp.euredomain.de`)"

can i just add the Domain and Sub-Domain in the same line like the first one?

Try it, add domains to both .rule lines.
