alt Hacker News| Since emails are sent from the individual’s email account, they are already verified.
This is not how email works, though.

+1, Even if they validate DKIM/SPF+alignment (aka DMARC) that would only verify the domain. There is no local part verification possible for the receiver, the sending server needs to be trusted with proper auth
This.
I wonder if it is a generation gap thing. The young folks these days have probably used only Gmail, Proton or one of these big email services that abstract away all the technical details of sending and receiving emails. Without some visibility into the technical details of how emails are composed and sent they might not have ever known that the email headers are not some definite source of truth but totally user defined and can be set to anything.
