How to Install Postorius on macOS

Postorius is a web-based user interface for the email list management software Mailman 3. In this tutorial, you will learn how to install Postorius on macOS.

Step 1: Install Mailman 3

Before installing Postorius, you need to install Mailman 3. You can use the following command to install Mailman 3 using Homebrew:

brew install mailman

Step 2: Install Postorius

You can install Postorius using pip, the package installer for Python. First, you need to create a virtual environment to isolate Postorius from other Python packages. You can use the following commands to create and activate a virtual environment:

python3 -m venv postorius-venv
source postorius-venv/bin/activate

Next, use pip to install Postorius:

pip install postorius

Step 3: Configure Postorius

You need to configure Postorius to connect to Mailman 3. Postorius expects Mailman 3 to be available at http://localhost:8001/. You can use the following command to start Mailman's built-in web server:

mailman info

You should see a message similar to the following:

Web interface is at http://localhost:8001/.
REST API is at http://localhost:8001/3.1/.

If you see a different URL, you can specify it when starting Postorius in the next step.

Step 4: Start Postorius

You can start Postorius using the following command:

postorius start

By default, Postorius will connect to Mailman 3 at http://localhost:8001/. If your Mailman 3 server is running on a different URL, you can specify it using the --mailman-url option:

postorius start --mailman-url http://mailman.example.com/

You should see a message similar to the following:

Starting Postorius 2.3.3 on http://localhost:8000/
Quit the server with CONTROL-C.

Postorius is now running and accessible at http://localhost:8000/.
