This cannot be done simply with the current version of mm-handler in
contrib -- it requires several code changes and would affect all actions
for <listname-action at lists.example.org>.  That would have bad effects on
VERP bounce handling, for example.

Here is an update to mm-handler which might address this adequately.  I
no longer use mm-handler myself (despite having written it), so I can't
test this short of installing a new Mailman instance.  Can someone on
the list test it?

Since it's contrib and not supported, maybe it would be reasonable to
put the update into the 2.1.10 release -- provided someone can declare
that it works. :)  Otherwise feel free to post it on the wiki.
