Fixing Email Authentication Not Verified on Google Workspace

Email authentication is a critical aspect of email security, helping to protect your domain from spoofing and ensuring your emails reach the intended recipients’ inboxes. However, sometimes, you may encounter issues where your email authentication is not verified on Google Workspace. This guide will walk you through the steps to diagnose and fix these issues.

What is Email Authentication?

Email authentication involves various protocols that verify the sender’s identity and ensure the email has not been tampered with during transit. The primary protocols used in email authentication are SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).

Common Issues with Email Authentication on Google Workspace

  1. Incorrect DNS Records: If the SPF, DKIM, or DMARC records are not correctly configured in your domain’s DNS settings, email authentication will fail.
  2. Propagation Delays: Changes to DNS records can take up to 48 hours to propagate. During this time, email authentication might not be verified.
  3. DKIM Signing Not Enabled: If DKIM signing is not enabled in the Google Admin console, your emails will not be authenticated using DKIM.
  4. Configuration Errors: Typographical errors or misconfigurations in your DNS records can cause authentication to fail.

Step-by-Step Guide to Fixing Email Authentication Issues

Step 1: Verify Your SPF Record

  1. Access Your Domain’s DNS Settings:
    • Log in to your domain registrar’s account.
    • Navigate to the DNS management section.
  2. Check your SPF record:
    • Ensure you have a TXT record with the value: v=spf1 include:_spf.google.com ~all.
    • If the SPF record is missing or incorrect, add or update it.
  3. Save and Verify:
    • Save the changes and verify that the SPF record is correct using an SPF checker tool.

Step 2: Enable and Verify DKIM

  1. Log in to the Google Admin Console:
    • Go to admin.google.com and log in with an admin account.
  2. Navigate to DKIM Settings:
    • Go to Apps > Google Workspace > Gmail > Authenticate email.
  3. Generate DKIM Keys:
    • If DKIM is not enabled, click “Generate new record.”
    • Select your domain and generate the DKIM keys.
  4. Add DKIM Record to DNS:
    • Copy the generated DKIM TXT record.
    • Go to your domain’s DNS settings and add the DKIM record.
  5. Start Authentication:
    • Return to the Google Admin console and click “Start authentication.”

Step 3: Configure and Verify DMARC

  1. Create a DMARC Record:
    • In your domain’s DNS settings, add a new TXT record with the name _dmarc.
  2. Add DMARC Policy:
    • In the value field, enter: copy codev=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-forensics@yourdomain.com; pct=100;
      • v=DMARC1: Specifies the DMARC version.
      • p=none: No action is taken, just monitoring.
      • rua: Aggregate reports email address.
      • ruf: Forensic reports email address.
      • pct=100: Apply the policy to 100% of emails.
  3. Save and Verify:
    • Save the changes and verify the DMARC record using a DMARC checker tool.

Step 4: Monitor and Troubleshoot

  1. Check DNS Propagation:
    • One DNS propagation checker tool to ensure your DNS records have propagated globally.
  2. Monitor Emaemailports:
    • Regularly check your DMARC reports to monitor authentication results and identify any issues.
  3. Adjust PolipoliciesNeeded:
    • Based on the reports, adjust your DMARC policy to enforce stricter rules (p=quarantine or p=rejector) you gain confidence in your configuration.
