DMARC fail Gmail: Causes

There are several reasons why an email may fail DMARC authentication. As previously stated, the most typical reason is that the email was received from a fake address.

There are, however, other possible causes of DMARC failure, such as:

• DMARC alignment failure:

  The email’s “From” address does not match the domain that is sending the email, which might happen if we use a third-party email provider like Gmail or Outlook to send email on behalf of the domain.
• Improper DMARC alignment mode:

  The “From” addresses match, however, DMARC is not properly set can also trigger the DMARC fail Gmail error.
• Missing DKIM signature:

  The DKIM signature is a digital signature that is used to confirm that an email was sent from the domain that it purports to be from.

  If it is missing or incorrect, the DMARC fail message may be generated.
• It’s also conceivable that the problem is caused by a lack of DNS TXT entries. TXT records are used in Domain Name Systems (DNSs) to hold text-based data.

  As previously stated, the DMARC policy employs two TXT records: SPF and DKIM.

What is a DMARC fail?

DMARC will pass as long as SPF or DKIM both pass and align. A DMARC fail Gmail, on the other hand, might occur for a variety of reasons.

DMARC will fail if both authentication checks pass but do not align. DMARC will also fail if both align but do not pass authentication.

If we weren’t the ones sending the email, knowing this is excellent, especially if we have a quarantine or reject policy, because it means we’re getting closer to figuring out who is spoofing the domain.

Even if we are the sender, the mail may nonetheless fail DMARC. This indicates that the authentication policies are flawed.

This can have a detrimental impact on email delivery since inboxes cannot verify that we have allowed the emails.

General Troubleshooting for DMARC fail Gmail

Organizations will encounter a variety of challenges while attempting to repair a DMARC policy after initial establishment.

The following basic DMARC standards serve to establish the optimal troubleshooting practices:

• Verify and thoroughly examine SPF, DKIM, and DMARC policies.
• Set DMARC to monitor mode (p=none).
• Examine the DMARC data for many weeks to locate valid email sources that are being rejected.

  Update the relevant policy (SPF, DKIM, DMARC, or email vendor settings) to resolve rejection issues.

  <li?Following the resolution of valid email concerns
• Gradually change the DMARC settings to ‘p=quarantine’ or ‘p=reject’.
• Examine for any new rejection concerns.
• Steps should be repeated until all transmitting domains are validated, enforced, and properly secured.
• Check reports on a regular basis for IP address changes, new domain conflicts, and spoofing sites to report or ban.
