How to Install Postorius on NixOS Latest

Postorius is a web-based admin interface for Mailman 3, a free and open-source mailing list management system. If you are using NixOS latest, here is a step-by-step guide on how to install Postorius.

Prerequisites

Before you begin, make sure you have the following:

  • A NixOS latest installation
  • Root access or a user account with sudo privileges
  • A web server (such as NGINX) installed and running on your server

Steps

  1. Update the package list:

    sudo nix-channel --update
sudo nix-env -i mailman3-core mailman3-postorius

  2. Allow HTTP traffic to your server. To do this, you can open the firewall on your server by running the following command:

    sudo firewall-cmd --permanent --add-service=http
sudo firewall-cmd --reload

    If you are using a different firewall application, refer to its documentation on how to open the HTTP port.

  3. Configure mailman3-core by editing the following files:

    • /etc/mailman3/mailman.cfg
    • /etc/mailman3/smtp.cfg
    • /etc/mailman3/urls.cfg
    • /etc/postfix/main.cf

    You can refer to the Mailman 3 documentation for more information on how to configure these files: https://docs.mailman3.org/en/latest/

  4. Configure Postorius by editing the file /etc/postorius.cfg. Here, you can customize the Postorius settings, such as the site URL, default theme, and allowed languages.

  5. Start the Mailman 3 and Postorius services:

    sudo systemctl start mailman-web
sudo systemctl start mailman-mailinglists
sudo systemctl start postorius

  6. Verify that Postorius is running by accessing it in a web browser. Use the IP address or domain name of your server and add /postorius to the URL. For example:

    http://your_server_ip_or_domain/postorius

    You should see the Postorius login page. Log in using the Mailman 3 superuser email and password.

Congratulations! You have successfully installed Postorius on NixOS latest. Now you can start managing your mailing lists using this web-based admin interface.
