I am trying to get the cert. Pem and key.pem from Dokploy Traefik which is needed for the Stalwart Mail Server configuration. Any suggestions or alternatives will work.

Stalwart Compose

@SashaGoncharov19 Thank you for your advice.
There are a few issues, I faced during your suggestion.

Error response from daemon: invalid config for network x34ot36f3rwyfa16s07qhpt72: invalid endpoint settings: no configured subnet or ip-range contain the IP address 172.26.0.128

@ShubashBiswas Did you find a way to make it works ?

I didn't use Proxy for the email port's. For SSL and TLS I went to the DNS proxy inside the mail server.

services:
mailserver:
image: stalwartlabs/mail-server:latest
container_name: stalwart-mailserver
restart: unless-stopped
hostname: mail.domain.com
networks:
- proxy
volumes:
- /etc/localtime:/etc/localtime:ro
- data:/opt/stalwart-mail
labels:
- traefik.enable=true

  - traefik.http.routers.mailserver.rule=Host(`mail.domain.com`)
  - traefik.http.routers.mailserver.entrypoints=websecure
  - traefik.http.routers.mailserver.service=mailserver
  - traefik.http.routers.mailserver.tls.certresolver=production
  - traefik.http.services.mailserver.loadbalancer.server.port=8080

networks:
proxy:
name: traefik
external: true
