You're confusing submission with SMTP. I have a printer that sends me e-mail when it's out of paper, which it does by sending mail to my submission server, not directly to me. If I were checking DMARC on the messages, they would easily pass since the submission server adds DKIM signatures. >Then the client wants to implement DMARC >---------------------------------------------------------- > >d) The client develops a list of all of its third-party mailers and tells the >third parties to begin applying the client's >DKIM signature to their messages.

I believe that devices that send mail do what they've always done, send it to a submission server for further delivery. The "special box" has been there all along.
