Mailman - The GNU Mailing List Management System¶
Mailman is written in Python, a free object-oriented programming language. Python is available for all platforms that Mailman is supported on, which includes GNU/Linux and most other Unix-like operating systems (e.g. Solaris, *BSD, MacOSX, etc.). Mailman is not supported on Windows, although web and mail clients on any platform should be able to interact with Mailman just fine.
GNU Mailman 3 consists of a suite of programs that work together:
- Mailman Core; the core delivery engine. This is where you are right now.
- Postorius; the web user interface for list members and administrators.
- HyperKitty; the web-based archiver
- Mailman client; the official Python bindings for talking to the Core’s REST administrative API.
Only the Core is required. You can write or integrate your own web user interface or archiver that speaks to the Core over its REST API. The REST API is a pure HTTP-based API so you don’t have to use Python, or even our official bindings. And you can deploy whatever components you want using whatever mechanisms you want.
But we really like Postorius and HyperKitty and hope you will too!

The name of this software is spelled Mailman with a leading capital M but with a lower case second m. Any other spelling is incorrect. Its full name is GNU Mailman but is often referred colloquially as Mailman.
Mailman was originally developed by John Viega in the mid-1990s. Subsequent development (through version 1.0b3) was by Ken Manheimer. Further work towards the 1.0 final release was a group effort, with the core contributors being: Barry Warsaw, Ken Manheimer, Scott Cotton, Harald Meland, and John Viega. Since version 1.0 the project has been led by Barry Warsaw with contributions from many; see the ACKNOWLEDGMENTS file for details. Jeremy Hylton helped considerably with the Pipermail code in Mailman 2.0. Mailman 2.1 is primarily maintained by Mark Sapiro, with previous help by Tokio Kikuchi (RIP). Barry Warsaw is the lead developer on Mailman 3. Aurélien Bompard and Florian Fuchs lead development of Postorius and HyperKitty. Abhilash Raj is a core developer contributing to all the bits and maintains the CI infrastructure.
