Hi Ken
The order of these headers looks odd to me. It seems to be saying that
the DKIM signature was added to the message, then it was passed to a
Google MTA, then the DKIM and DMARC Authentication-Results were added,
then it was received by your MX server? Have you reordered these headers
at all? If so, what was the original order of the headers?
Thanks,
Nick.
