If receivers lookup the Author: domain too, they can evaluate

Since there is no authentication or alignment associated with the
Author field, I don't know how they can be evaluated.
Receivers can evaluate the Author: domain just like they would do if it
were the From: domain.
So you want to define DMARC as applying to both the From: field and the
Author: field? That will defeat the benefit intended for the Author: field.
As a new field, Author: doesn't wear a
reliable-id trophy, hence receivers may refrain to apply policy
dispositions. However, the result of the evaluation, conveyed through
aggregate report, can tell MLMs if rewriting From: was necessary.
How, exactly?
