There have been several conversations in the past about the fact that even across virtual domains, all lists must have unique names, and ways to fix this.

In March of 2006, there was a large discussion which culminated in Hans Ulrich Niedermann posting links to the patches he was working on in this message:

http://mail.python.org/pipermail/mailman-developers/2006-March/018629.html

Unfortunately, neither the machine hosting the download page nor the one hosting the Git repository are responding to connections.

Does anybody know if Hans made more progress on the patches after he made that post? And more importantly, since neither Google nor Archive.org happened to crawl the patch files, does anyone have copies?

As another aside, as noted in entry 4.47 in the Mailman FAQ ( http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq04.047.htp ) CPanel apparently has patched this functionality into Mailman, but decline to give back their changes. Given that Mailman is normally distributed under the GPL, the only way that could be kosher is if they made a deal to distribute it under a different license. Would anyone be able to speak to whether or not that is the case?
