Hello,
we use OpenDKIM to validate DKIM signatures for inbound messages. Works so far
as usual.
Of course, OpenDKIM add Authentication-Results header as defined per RFC 7601.
Before adding such header, OpenDKIM test any existent Authentication-Results
header if it
pretend to be generated from
Message-ID:
<934542802.10812.1678919922311.javamail.r...@rocketman-commercial--email-consumer--default-56.hbu-svc-rocketman-commercial--email-consumer--default.rocketman-commercial-production.svc.cluster.local>
Or is that REALLY your PTR records..
