How to publish a DMARC record

Publishing a DMARC record is the first step in deploying DMARC.

To create a DMARC record, use the dmarcian DMARC Wizard.  When you have the text of your DMARC record at your fingertips, follow these steps:

  1. Log in to your DNS management console.
  2. Navigate to the domain where you'll be publishing a DMARC record.
  3. Most DNS management consoles will ask for:
    • Hostname: this should be "_dmarc".  NOTE: the leading "underbar" character is required!
    • Resource type: this is "TXT", as DMARC records are published in the DNS as TXT resources.
    • Value: this is the DMARC record itself, of the form "v=DMARC1; p=none; rua=..."
  4. Save and you're done.

The results of doing the above will allow email receivers to query the DNS for your DMARC record at a location of "_dmarc.your-domain.com".
