DMARC record generator

DMARC tells receivers what to do with mail that claims to be from your domain but fails SPF and DKIM — and sends you reports about it.

Policy

Daily summaries of who sent mail as your domain. Separate several with commas.

  • Without rua you will not see who is sending as your domain. Add a reporting address before tightening the policy.
  • p=none only monitors. Move to quarantine once reports show your senders pass.

A safe order to roll it out

  • Week one: p=none with a reporting address. Read who is sending as you.
  • Once every real sender passes: p=quarantine, optionally at a lower percentage first.
  • When quarantine has been quiet: p=reject.

Make sure SPF and DKIM pass before enforcing, or your own mail goes to spam.
