Gnu mailman 3pl

A very specific topic!

GNU Mailman 3 is a popular open-source mailing list manager that allows users to create and manage mailing lists, as well as send and receive emails. Here's a brief overview of the 3PL (Third-Party List) feature in GNU Mailman 3:

What is 3PL?

In GNU Mailman 3, 3PL (Third-Party List) is a feature that allows you to create a mailing list that is managed by a third-party list server, rather than Mailman itself. This means that the list is hosted on a separate server, and Mailman acts as a proxy to manage the list.

Why use 3PL?

There are several reasons why you might want to use 3PL:

  1. Decentralized management: By hosting the list on a separate server, you can manage the list independently of Mailman.
  2. Customization: You can customize the list server to meet your specific needs, such as using a different email client or implementing custom list management features.
  3. Scalability: If your list grows rapidly, you can scale the list server to handle the increased traffic.
  4. Security: You can ensure that the list server is properly secured and compliant with your organization's security policies.
