carl, this is accounted for in the current working draft, not yet released.
as a general principle, dmarc doesn't modify the operation of underlying authentication mechanisms. so if a supported underlying authentication mechanism produces an aligned result in the normal course of its operation, it will be accepted by dmarc. so if you see other errors of omission, etc. such as this, please raise them. hope that helps. -p From: "Carl S.
