I sign everything, and make no effort to validate stuff on
the From: line.
They key point is that DKIM makes no statement about the basis by which a given
signature is made or not made, AND different signers do indeed have very
different criteria.
No doubt some do validate the From: field. Others merely mean "the message
went
through my MTA". Any assertion of From: field assessment is therefore far
outside the scope of the DKIM base specification.
