Mailman3 setup

Mailman3 is a popular open-source email list management system. Here's a step-by-step guide to setting it up:

Prerequisites

• A Linux-based server (e.g., Ubuntu, CentOS, Debian)
• Python 3.6 or later installed
• A database management system (e.g., PostgreSQL, MySQL)
• A web server (e.g., Apache, Nginx)

Step 1: Install Mailman3

1. Install the required packages:

   sudo apt-get update
   sudo apt-get install python3 python3-pip

2. Install Mailman3 using pip:

   sudo pip3 install mailman

   Step 2: Configure Mailman3

3. Create a new configuration file for Mailman3:

   sudo mailman configure --with-passwords

   This will create a mailman.cfg file in the /etc/mailman3/ directory.

4. Edit the mailman.cfg file to configure Mailman3:

   sudo nano /etc/mailman3/mailman.cfg

   Set the following options:

   [general]
   database_url = postgresql://username:password@localhost/mailman

   Replace username, password, and localhost with your database credentials and server name.

Step 3: Create the Database

1. Create a new database for Mailman3:

   sudo -u postgres createuser -s -r mailman
   sudo -u postgres createdb -O mailman mailman

2. Grant permissions to the Mailman3 user:

   sudo -u postgres psql -d mailman -c "GRANT ALL PRIVILEGES ON DATABASE mailman TO mailman;"

   Step 4: Initialize the Database

3. Initialize the Mailman3 database:

   sudo mailman init

   This will create the necessary tables in the database.

Step 5: Start the Mailman3 Service

1. Start the Mailman3 service:

   sudo systemctl start mailman

2. Enable the Mailman3 service to start automatically on boot:

   sudo systemctl enable mailman

   Step 6: Configure the Web Interface

3. Install the Mailman3 web interface:

   sudo pip3 install mailman-web

4. Configure the web interface:

   sudo nano /etc/mailman3/web.cfg

   Set the following options:

   [web]
   host = localhost
   port = 8001

5. Start the web interface:

   sudo mailman-web start

   Step 7: Test Mailman3

6. Create a new list:

   sudo mailman create mylist

7. Add a member to the list:

   sudo mailman add mylist [email protected]

8. Send a test email to the list:

   sudo mailman send mylist "Hello, world!"

   This should send an email to the list with the subject "Hello, world!".

That's it! You should now have Mailman3 set up and running on your server.
