Sorry, but you are wrong. When I have a reject policy for dmarc and send
to a mailing list, I get the same mail back from the list. SPF does not
pass, because the list server is not of my domain. dkim should pass
because the signature is ok. OpenDKIM does so, but OpenDMARC fails and
refuses that mail. Thats NOT OK!
