The receiver sees CompanyA in the from field. Do they trust MailChimp? If they do, let MailChimp create a DKIM key and sign the messages they send on behalf of CompanyA as: DKIM-Signature: v=1; d=CompanyA; s=MailChimp; ... To publish the public key that MailChimp will hand out as said selector is CompanyA's act of faith. Indeed, the effect is not much different than authorizing specific domains through DNS. Best Ale --
