Here's another example of a DMARC "failure" when mail (from me) is passed on to an ESR subscriber. This time the text of the "failure" report includes more headers (see below).
Note that our SPF and DKIN both pass (ARC-Authentication-Results) when they get to mx.google.com, but apparently antispamcloud.com looks at the SPF and DKIM for us (iment.com), instead of the SPF & DKIM for mail.mozilla.org. Is this something that Mozilla can remedy? Or, if so many email providers can't deal with the behavior of the ESR mailing list server, I don't know what to do except downgrade our DMARC action from "Quarantine" (much less "Reject") back to "None" (which it was until quite recently).
