Did you restart Mailman after installing the python-dns package?

Yes, I still think that. If you did restart Mailman and the package is
available, something should be logged unless the DNS lookup of DMARC
policy for the From: domain succeeds and doesn't find a p=reject (or
quarantine).

I have attached a patch to Mailman/Utils.py which is a fix for
<https://bugs.launchpad.net/mailman/+bug/1324541> which will log the
unavailability of DNS lookup.
