Isn't the ideal objective of DMARC to be so reliable that *everybody* uses it with p=reject. At that point, 5322.From addresses will all be munged. Why not skip the complexity and start munging them all now? I'm not particularly keen on this as a solution to DMARC's MLM problem, but there's no doubt that it would settle the issue.
