Debian has already committed (prior to any of this) to making their
mailing lists DMARC compliant by ceasing the alteration of mail
passing through their lists.

It is an extreme pity these mailing list providers have demonstrated
such an extreme disregard for standards which aim to eliminate
forgeries and ensure people cannot be digitally misrepresented. This
is why we had to change Bugzilla a while back to send as
bugzilla_noreply at instead of the acting user's email address -
because Yahoo's enforcement policy meant GMail always placed mail from
Yahoo users in the spam folder.

I'll grant an extension until 31 January, however I would like to see
commitments from some of these to improve their infrastructure.
