In this tutorial, we will guide you through the process of installing Postal on NixOS latest, which is a simple, elegant and reliable open-source mail server that is designed for modern-day e-commerce businesses.
Before we begin with the installation process, there are certain prerequisites that need to be fulfilled:
Firstly, we need to install the Postal dependencies. These can be done by adding the following line to your NixOS configuration file in the imports section:
{pkgs = import <nixpkgs> { }; }:
[
# ...
pkgs.postgresql_13
pkgs.libmaxminddb
]
This will install PostgreSQL v13 and libmaxminddb packages.
After making the changes in the configuration file, rebuild the nixos system by running the following command:
$ sudo nixos-rebuild switch
Once the Postal dependencies have been installed, we can now proceed with the installation of Postal.
Run the following commands in your terminal:
# Install Postal networking dependencies
$ sudo nix-env -iA nixos.networking.libnetfilter_conntrack
# Clone Postal repository
$ git clone https://github.com/atech/postal /opt/postal
# Install Postal dependencies
$ cd /opt/postal
$ sudo gem install bundler --no-ri --no-rdoc
$ sudo bundle install --deployment --without test development mysql
# Configure Postal
$ sudo postal initialize-config
# Edit Postal configuration
$ sudo nano /opt/postal/config/postal.yml
# Assign a secret token for security
$ sudo postal make-token
# Configure Postal as a service
$ sudo systemctl enable postal
$ sudo systemctl start postal
# Verify the installation
$ sudo postal status
The above commands will install Postal on your NixOS latest system.
That's it! You have successfully installed Postal on NixOS, and your system is now ready to send and receive emails. In case you face any issues while following this tutorial, feel free to refer to the official documentation of Postal or seek help from our support team.
