I was thinking about the opposite case, where it *doesn't* get munged.
Temporary brain fart -- that is OK because the *From* domain can't be
p=reject, so no problem with DMARC even though Yahoo! has draconian
policies.  (Of course the user must deal with rejects due to Yahoo!'s
AUP, but that doesn't have anything to do with DMARC.)

This stuff is just hard to think about. :-(
