>I think it’s critical to DMARC that receivers do things like evaluate and report on DKIM whether or not SPF passes and is alignment. Without this, it would make it harder for senders to notice and remediate gaps in their authentication. Since there’s not a downside (that I know of), I’d say this should be a MUST if at all possible.


What is the interoperability problem that happens if evaluators don't do that?
