Mailu is a free, secured and fully-featured mail server software. In this tutorial, we'll walk you through installing Mailu on Fedora CoreOS.
Before we proceed to the installation, let's ensure we have the following:
It's recommended to update your system's packages and dependencies before installing Mailu. To do this, open your terminal and run:
sudo dnf update
Enter your password when prompted and wait for the command to successfully finish.
Mailu runs on Docker containers. Therefore, we'll need to install Docker and Docker-compose on our system. To install Docker on Fedora CoreOS, run the following commands:
sudo dnf install -y podman
sudo systemctl enable podman.service
sudo systemctl start podman.service
sudo dnf install -y docker-compose
Once installed, test to make sure docker and docker-compose are correctly installed by running:
docker --version
docker-compose --version
With Docker and Docker-compose installed, the next step is to clone the Mailu repository.
git clone https://github.com/Mailu/Mailu.git
Navigate to the cloned directory using:
cd Mailu/
We will need to update some values on the mailu.env configuration file before proceeding. Run:
cp mailu.env.sample mailu.env
nano mailu.env
Nano is a text editor that comes with Fedora CoreOS. If you don't have nano installed, you can use another text editor like Vim.
Locate the lines below and update the values accordingly:
MAILU_HOSTNAME=mail.example.com
PW_SECRET=CHANGE_ME
Change the MAILU_HOSTNAME value to your domain's name, and set a secure value for PW_SECRET.
Save and exit the mailu.env file.
To start Mailu, run the following command from the Mailu directory:
sudo docker-compose up -d
The command will start the Mailu service in detached mode (in the background). It may take a few minutes to download and configure all the necessary images.
Once you have the services running, you can check the status of the Mailu services with:
sudo docker-compose ps -a
You should see a list of services runnings. Look for five services with 'mailu' as a prefix:
You can access the web interface to create new users and domains by visiting http://your-domain.com/admin. Don't forget to replace your-domain.com with the MAILU_HOSTNAME you set in the previous step.
We've successfully walked through the process of installing Mailu on Fedora CoreOS. You now have a secured email server running on your machine. You can visit the Mailu Documentation to learn more about the various Mailu settings and configurations.
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!
Alternatively, for the best virtual desktop, try Shells!
