I see. As I am sure everyone has noticed, I am a complete newbie to SPF/DKIM/DMARC (and a lot of other things.) Understanding your message, creating a DMARC with "none" policy would not have any downside? When you say "reporting", what type of reporting would that be and how could I benefit from such reporting?
