Colibri is a mailing list manager, with an emphasis on the Web frontend, done with Django/Python. It is similar to GNU mailman or majordomo, but in a somewhat more modern way.
Information regarding Project Releases and Project Resources. Note that the information here is a quote from Freecode.com page, and the downloads themselves may not be hosted on OSDN.
This release added more checks when the daemon starts, an upgrade to Django 1.3, and switched to a userlessname' django application instead of home-made hacks for email-based login. CKEditor is now used instead of the buggy TinyMCE. A default robots.txt and favicon.ico are now provided.
Bugs were fixed. People can now browse the list of subscribers when allowed to by the list config. A README and an example of local_config.py were added.
The Web interface can handle multiple domains and multiple email messages for an account, display archives, and import from sympa (configuration, subscribers list, and archive).
