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.
Before installing Postorius, you need to install Mailman 3. You can use the following command to install Mailman 3 using Homebrew:
brew install mailman
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
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.
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/.
In this tutorial, you learned how to install Postorius on macOS. With Postorius, you can manage your Mailman 3 email lists using a web-based user interface.
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!
