Mail Server Pre-Install Setup

To use this template, you need to perform some actions before installing it.

The minimal DNS configuration

This example shows you a set of records for one domain. Each domain that is added needs at least this set of records to function correctly.

# Name              Type       Value
mail                IN A       1.2.3.4
autodiscover        IN CNAME   mail.example.org. (your ${DMS_HOSTNAME})
autoconfig          IN CNAME   mail.example.org. (your ${DMS_HOSTNAME})
@                   IN MX 10   mail.example.org. (your ${DMS_HOSTNAME})

SSL/TLS

Dokploy uses Traefik to generate certificates for your containers. There's a problem here, the domain must be configured on another service for Traefik to request it from Let's Encrypt (i.e. Traefik will not issue a certificate without a request from the service/router).

Therefore, you need to create a basic Compose project and add your domain to this project to issue a certificate. Here is an example of a Compose project:

services:
  whoami:
    image: docker.io/traefik/whoami:latest
    networks:
      - dokploy-network

Then go to the Domains tab, click Add Domain, select whoami in the Service Name field, enter your domain (mail.example.com) in the Host field and set the Container Port field to 80. In the HTTPS line below, enable this value and select Letsencrypt (Default).

Then save it, and in the General tab, click Deploy
