You clearly don't need qmail-to-mailman.py, and while Debian seems to
like postfix-to-mailman.py (which is not distributed even as
contributed source by the GNU Mailman project), I don't recommend it.

This is a Debian packaging issue. If you wish to install Debian's
Mailman package, you'll have to take this up with Debian.

If you download and install the 2.1.13 tarball from
<https://launchpad.net/mailman/2.1/2.1.13> or
<http://ftp.gnu.org/gnu/mailman/>, it will be less convenient, but we
can help you with any installation issues.
