It would also violate the DKIM specification.


Not if its a DKIM POLICY based reason. I presumed he meant RFC 5617 DKIM=DISCARDABLE|ALL where From: and DKIM-Signature: or lack there of, headers is all that is needed.

Failed DKIM validation is to be treated as if no signature is present.

which violates RFC 5617 DKIM=DISCARDABLE policy which would justify a SMTP level rejection or POST SMTP message acception silent discard.
