Oh, an your reply was an invalid email and ended up in my spam-box: From: David Hildenbrand <da...@redhat.com>
but you apparently didn't use the redhat mail system, so the DKIM signing fails
dmarc=fail (p=QUARANTINE sp=QUARANTINE dis=QUARANTINE)
header.from=redhat.com
and it gets marked as spam.
I think you may have gone through smtp.kernel.org, but then you need
to use your kernel.org email address to get the DKIM right.
