## Mailcow derrière Traefik

Modifier le fichier de configuration `mailcow.conf`afin que nginx écoute sur les `8080` et `8443`

```shell
HTTP_PORT=8080
HTTP_BIND=127.0.0.1

HTTPS_PORT=8443
HTTPS_BIND=127.0.0.1
```

Dans l'arborescence de mailcow créer un fichier `docker-compose.override.yml` et placer les lignes suivantes.

```yaml
services:
  nginx-mailcow:
    expose:
      - 8080
    labels:
      - traefik.enable=true
      - traefik.http.routers.nginx-mailcow.rule=HostRegexp(`{host:(autodiscover|autoconfig|webmail|mail|email).+}`)
      - traefik.http.routers.nginx-mailcow.entrypoints=https
      - traefik.http.routers.nginx-mailcow.rule=Host(`${MAILCOW_HOSTNAME}`)
      - traefik.http.routers.nginx-mailcow.tls=true
      - traefik.http.routers.nginx-mailcow.tls.certresolver=le
      # Uncomment to use wildcard cert:
      # - traefik.http.routers.nginx-mailcow.tls.domains[0].main=example.com
      # - traefik.http.routers.nginx-mailcow.tls.domains[0].sans=*.example.com
      - traefik.http.routers.nginx-mailcow.service=nginx-mailcow
      - traefik.http.services.nginx-mailcow.loadbalancer.server.port=8080
      - traefik.docker.network=traefik
    networks:
      - traefik

  certdumper:
      image: humenius/traefik-certs-dumper
      network_mode: none
      command: --restart-containers mailcow_postfix-mailcow_1,mailcow_dovecot-mailcow_1,mailcow_nginx-mailcow_1
      volumes:
        - /home/draconis/traefik/certificates:/traefik:ro
        - /var/run/docker.sock:/var/run/docker.sock:ro
        - ./data/assets/ssl:/output:rw
      environment:
        - DOMAIN=${MAILCOW_HOSTNAME}
        # If using wildcard certs instead of an explicit host cert,
        # use following line instead with just the TLD so certdumper
        # is able to find the cert.
        # - DOMAIN=YourDomain.com

networks:
  traefik:
    external: true
