We already have DKIM which does exactly what you describe.
- pilsetnieks 8y agoDKIM proves that it's someone with access to your domain, not you specifically.
- ngrilly 8y agoYes, and this is in line with the article we are commenting, which talks mostly about authentifying the sending organisations and not individuals.
- NoGravitas 8y agoActually it proves even less than that --- it proves that it's someone with access to the domain that it was sent from. And if that's not amazon.com, but instead amazon-account-services.ru, then DKIM will happily report that the message is valid.
