Installing docker-mailserver on Arch Linux

In this tutorial, we will be installing the docker-mailserver on Arch Linux. This guide assumes that you have already installed Docker on your system. If you haven't installed it already, you can follow the official Docker documentation for installation instructions.

Step 1: Clone the Repository

First, we need to clone the docker-mailserver repository from GitHub. We'll be using the "edge" branch for this tutorial.

git clone --single-branch --branch edge https://github.com/docker-mailserver/docker-mailserver.git

After cloning, navigate to the repository directory:

cd docker-mailserver

Step 2: Customize the Environment

Next, we need to customize the environment by creating an .env file.

cp env-dist .env

Edit the .env file with your desired settings. Take note that some of the important and required fields to fill in include:

• HOSTNAME: This should be the domain name or IP address of the server.
• POSTMASTER_ADDRESS: The email address of the postmaster.
• ADDITIONAL_SAN: Additional subject alternative names for the SSL certificate.

Step 3: Generate SSL Certificates

Run the command below to generate self-signed SSL certificates:

make create-certs

Step 4: Create the container

Now, we can create the container and start the mailserver:

docker-compose up -d mail

This will create the mailserver container and start all necessary services.

Step 5: Verify

To verify that the mail server is working properly, you can open a terminal and type:

docker-compose logs -f mail

You should see logs showing the mail server starting up.

Congratulations, you have successfully installed and started the docker-mailserver on Arch Linux.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
