all this is solved if maillists stop dkim signing of non origination postings
and only do the arc sealing so all dmarc testers can see originating spf, dkim
pass
ARC doesn't exclude DKIM. Actually, the latter has a larger use base and it
would be an error to stop supporting it.
take sendgrid, thay forwarded netflix phishing emails, and thay belived dmarc
protected there ignorance to some kind out off there services
never trust a forwarding server that does there own dkim signing, period
We always knew that verified authenticity wouldn't imply trust, irrespective of
forwarding.
dmarc needs openARC testing to all above to work, then maillist can break
maillists to there own stupid needs without breaking dkim cant be verified on
dmarc recipient servers
ARC is not a part of DMARC, despite the acronym being a substring.
