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

That turns out not to be the case. The GPL does *not* require giving back (and according to the free software definition, a license that requires giving back is *non-free*). What the GPL requires is "giving forward" (ie, to the users of the software). It seems that the users of the software are the owners of the hardware on which it runs (the so-called "ASP loophole").

So what you need to do is find a cPanel licensee who has requested source from cPanel.

At least one person possessing cPanel source has posted to the list in the last year or so, but there didn't seem to be much excitement about it.
