Why or why not?
I think for a PSD that sends mail, the current definitions would require Mail >From for SPF or d= for DKIM to be the same because they wouldn't end up having the same org domain. It might be simple enough to say to ignore psd=y or a lower level psd=n if the 5322.From has a domain with psd=y (they can always set strict alignment if they don't want lower level stuff to match).
