It's not clear to me which you mean by author's domain? Are you suggesting
that the email originator include both Author and From and DKIM sign Author
instead of From?
Yes he is. Please see:
Email Author Header Field
https://datatracker.ietf.org/doc/rfc9057/
Abstract
Internet mail defines the From: header field to indicate the author
of the message's content and the Sender: field to indicate who
initially handled the message on the author's behalf. The Sender:
field is optional if it has the same information as the From: field.
This was not a problem until development of stringent protections on
use of the From: field. It has prompted Mediators, such as mailing
lists, to modify the From: field to circumvent mail rejection caused
by those protections. In effect, the From: field has become
dominated by its role as a handling identifier.
The current specification augments the altered use of the From: field
by specifying the Author: field, which ensures identification of the
original author of the message and is not subject to modification by
Mediators. This document is published as an Experimental RFC to
assess community interest, functional efficacy, and technical
adequacy.
