I think this is the first mention of postfix-to-mailman.py in this
thread. My advice to ensure that the list domain was in mydestination
was based on my incorrect assumption that you were using aliases.

You and your sysadmin may find the FAQ at <http://wiki.list.org/x/EYDt>
and the post at
<http://mail.python.org/pipermail/mailman-users/2012-September/074017.html>
which is linked therefrom to be of interest.
