How do I configure DMARC?

Updated Nov 2, 2026

DMARC tells providers what to do when SPF and DKIM do not match your From domain. In MailRush's DNS setup it is marked Advisory: sending does not depend on it, but providers expect it.

Steps

  1. Open the account's View DNS in Email Accounts and find the DMARC record card.
  2. If your domain already has a valid DMARC record, keep it.
  3. If it has none, publish the Value to publish as a TXT record with the name shown (_dmarc).
  4. Click Check DNS.

Check it with a real email

  • Send a test email to a Gmail address, open it, choose Show original and look for SPF, DKIM and DMARC "PASS".
