A lot of tiny non-profits like Girl Scout troops use email addresses at webmail providers and send their announcements through ESPs like Constant Contact and Mailchimp. This is yet another situation where DMARC can't describe an entirely normal mail setup. Constant Contact apparently got Yahoo to give them a signing key, at least temporarily, but that doesn't scale.
