ARC is what you need, it a similar signing as DKIM, but resigns a message. https://en.m.wikipedia.org/wiki/Authenticated_Received_Chain https://en.m.wikipedia.

- AceJohnny2 4y agoInteresting. I see a gotcha though: > Validating an ARC chain only makes sense if the receiver trusts the ARC signers. In fact, an ARC chain can be counterfeited,[3] so ARC processing applies when receivers trust the good faith of ARC signers, but not so much their filtering practices. Is there any documentation on how GMail and Hotmail onboard a ARC-using domain? Their documentation is very... sparse.
- Avamander 4y agoThe same way they're gathering intel on domain/IP trustworthyness.
