Mailu is a free and open-source, self-hosted email server that provides a complete solution for email hosting. In this tutorial, we will guide you through the process of installing Mailu on nixOS Latest.
Before proceeding with this tutorial, ensure that your system meets the following requirements:
Open the terminal and switch to the root user by running the following command:
sudo -s
Next, we will add the Mailu repository to our system's configuration file. Open the file /etc/nixos/configuration.nix
with your preferred text editor:
nano /etc/nixos/configuration.nix
Add the following lines to your configuration file:
nixpkgs.config.packageOverrides = pkgs: {
mailu = pkgs.callPackage (builtins.fetchTarball {
url = "https://github.com/Mailu/Mailu/archive/master.tar.gz";
sha256 = "0586r1B6UgGmzkQJwzHm8W4LgIvqb0q3/Hp29Joa8jg=";
}) { };
};
Save the file and exit your text editor.
Update your system's packages and repositories:
nix-channel --update nixpkgs
nix-channel --update mailu
Install Mailu:
nix-env -iA nixpkgs.mailu
Navigate to the Mailu configuration folder:
cd /etc/mailu/
Rename the config.inc.sample.py
file to config.inc.py
:
mv config.inc.sample.py config.inc.py
Open the config.inc.py
file using your preferred text editor:
nano config.inc.py
Update the following settings in the config.inc.py
file according to your requirements:
DOMAIN = 'example.com'
DBPASSWORD = 'your_database_password'
Save your changes and exit your text editor.
Start the Mailu Docker containers by running the following command:
docker-compose up -d
Verify that Mailu is running by checking its status:
docker-compose ps
If everything is working correctly, you should see the following output:

Congratulations! You have successfully installed and configured Mailu on nixOS Latest. You can now configure your mail client and start sending and receiving emails.
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!
