@freddieleeman To clarify, STOP DOING DMARC is mostly a joke, but I am also serious about not running DMARC software on the server which implements all sorts of policies and generates DMARC reports as it adds a lot of complexity. We can do this because we don't care about federating with non-secure servers not supporting DKIM and hopefully it results in faster adoption of DKIM among servers which want to federate with us.
