How to Install Postorius on OpenBSD

Postorius is a web user interface for Mailman 3, the popular mailing list management software. In this tutorial, we will cover the steps to install Postorius on OpenBSD.

Prerequisites

Before you start, ensure that you have the following requirements met:

• A server running OpenBSD with sudo access
• Python 3 installed on the server
• pip package manager installed on the server

Step 1: Install Required Dependencies

First, we need to install some dependencies required for Postorius on OpenBSD.

To do this, open your terminal and run the following command:

sudo pkg_add py3-psycopg2 py3-pillow py3-django py3-django-auth-ldap py3-django-crispy-forms py3-django-haystack py3-django-multiselectfield py3-werkzeug

Step 2: Install Postorius

Once the dependencies are installed, we can proceed to install Postorius.

To install Postorius, open your terminal and run the following command:

sudo pip install postorius

This will install the latest version of Postorius and its dependencies.

Step 3: Configure Postorius

Next, we need to configure Postorius to work with Mailman 3.

To do this, we need to create a configuration file for Postorius. You can create a file named postorius.cfg in the /etc/mailman3 directory with the following contents:

[general]
# URL to Mailman's REST API.
DEFAULT_URL = 'http://localhost:8001'

# URL prefix for Postorius
SITE_URL = 'http://localhost:8000'

# Site name.
SITE_NAME = 'Mailman 3'

# Default sender email for notification emails.
SERVER_EMAIL = 'mailman@example.com'

# Default email for technical support.
TECH_SUPPORT_EMAIL = SERVER_EMAIL

# CSRF token expiration time.
CSRF_COOKIE_AGE = 3600

# Secret Key.
# This key should be kept secret and unique for each installation.
SECRET_KEY = 'rH0pYWMbmglf8LY7VQ2XhwnPsPrVuD2v'

# Log level.
LOGGING_LEVEL = 'INFO'

[database]
# Configuration for PostgreSQL database.
ENGINE = 'django.db.backends.postgresql'
NAME = 'mailman'
USER = 'mailman'

[security]
# Require secure connections for all views.
SECURE_SSL_REDIRECT = False

# Disable frame embedding.
X_FRAME_OPTIONS = 'DENY'

# Enable HSTS.
SECURE_HSTS_SECONDS = 3600

# Enable CSP.
CSP_DEFAULT_SRC = ["'self'"]
CSP_IMG_SRC = ["'self'", 'data:']

You can modify the values to suit your needs.

Step 4: Start Postorius

Finally, we can start Postorius.

To start the development server, run the following command:

sudo postorius start

This will start Postorius on http://localhost:8000. You can access the web interface by opening your web browser and entering http://localhost:8000 in the address bar.
