Solid base — one policy step remains.
redhat.com publishes an enforcing DMARC policy, so mail that forges its domain is quarantined or rejected at the recipient.
Your SPF setup is using the maximum number of allowed DNS lookups, so it is very close to the limit and may stop working if anything else is added later. This matters because mail providers can reject or distrust your messages if SPF fails. The fix is to simplify the SPF path by reducing DNS lookups, usually by replacing chained includes or redirects with a flatter setup.
