Aside from DMARC, it appears that @redhat.com outbound messages come
from an AWS IP that's listed in Spamhaus:

 Received: from mx-prod-mc-05.mail-002.prod.us-west-2.aws.redhat.com
         (ec2-54-186-198-63.us-west-2.compute.amazonaws.com [54.186.198.63]) by
         relay.mimecast.com with ESMTP with STARTTLS (version=TLSv1.3,
         cipher=TLS_AES_256_GCM_SHA384) id us-mta-631-aPSluwObPhGfMI0aAcFHew-1;
         Thu,
         25 Jun 2026 10:13:29 -0400

$ dig +short 63.198.186.54.zen.spamhaus.org a
127.0.0.3

Maybe somebody at Red Hat can pass that along to corporate IT?
