DMARC Record Checker: Verify Your Domain’s DMARC Configuration Instantly

Check if your domain has a valid DMARC record and ensure your email authentication setup is secure.

What Does DMARC Record Checker Do?

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a crucial email authentication standard that protects your domain from phishing and spoofing.

The DMARC Record Checker checks if your domain’s DNS has a valid DMARC record. It checks the record syntax, policy type, and reporting tags to assert your outgoing emails are authenticated and protected.

You can scan your domain to

  • Check if your domain has an active DMARC record
  • Verify your DMARC syntax and tags
  • Identify policy misconfigurations or missing parameters

Tags Included in DMARC Record

DMARC tags help email receivers to check for DMARC and handle emails that fail the DMARC authentication. Following are the tags that are used in the DMARC Record:

Mandatory Tags in DMARC TXT Record

V:

This tag identifies the record that has been retrieved as a DMARC record. This tag must be first listed in the DMARC record and its value must be DMARC1.

P:

'p' tag indicates that the requested DMARC policy that your mailbox providers should apply when an email fails the DMARC authentication and alignment checks.

There are three types of DMARC policies that can be implemented for your domain:

None:

If this policy is active, your internet service provider will not do anything with emails that fail authentication and they will be delivered in the recipient's inbox. This is also referred to as the monitoring mode. Using this policy, one can analyze the DMARC report and know exactly who has been using your domain to send emails on your behalf.

Quarantine:

When the Quarantine policy is active, the ISP will move the unauthenticated emails to the spam folder. These emails can then be quarantined. They can then be analyzed in order to identify if these are genuine or not.

Reject:

In the presence of this policy, all emails that fail the DMARC authentication will be rejected by the ISP. These emails will not show up in the receiver's mailbox. However, this policy should be implemented very carefully as along with illegitimate emails sent from spoofers, the ISP can also block emails sent from sources not on your whitelist when this policy is active.

These policies can be appropriately set for your email domain by using the DMARC deployment tool TDMARC.
