How to Fix “No DMARC Record Found”

If you’ve received a message or alert saying “No DMARC record found,” don’t worry—this guide will walk you through everything you need to know to fix the issue. Let’s start by understanding what a DMARC record is, why it’s important, and then we’ll dive into the step-by-step solution to fix the “No DMARC record found” issue.

What is a DMARC Record?

DMARC stands for Domain-based Message Authentication, Reporting & Conformance. It’s a protocol that helps protect your email domain from being used for phishing and other malicious activities like email spoofing. When you set up a DMARC record for your domain, you’re telling email servers how to handle messages that claim to be from your domain but fail authentication checks like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail).

In simple terms, a DMARC record helps you:

• Prevent Email Fraud: By verifying that emails sent from your domain are legitimate.
• Improve Email Deliverability: By making it more likely that your emails will land in the recipient’s inbox, not in the spam folder.
• Gain Visibility: By providing reports that show you who is sending emails from your domain, whether they are legitimate or not.

Why “No DMARC Record Found” is a Problem

If your domain doesn’t have a DMARC record, it means you’re missing out on these protections. Without a DMARC record:

• Your domain is more vulnerable to being spoofed. Scammers can send emails that look like they’re coming from your domain, tricking recipients into believing they’re legitimate.
• You won’t have visibility into potential email fraud involving your domain.
• Your emails might end up in spam folders, affecting your communication and business reputation.

Step-by-Step Guide to Fix “No DMARC Record Found”

Step 1: Understand Your Current Email Setup

Before you set up a DMARC record, it’s important to know:

• Who sends emails on behalf of your domain: This could include your own mail servers, third-party services like marketing platforms, or even your website’s contact forms.
• Your current SPF and DKIM settings: SPF and DKIM are authentication methods that DMARC relies on. Make sure these are configured correctly.

Step 2: Create a DMARC Record

A DMARC record is a simple text entry in your domain’s DNS (Domain Name System) settings. It tells email servers how to handle emails that fail SPF or DKIM checks.

Here’s how to create one:

• Log in to your DNS provider: This is usually where you manage your domain settings (e.g., GoDaddy, Namecheap, Cloudflare).

• Go to the DNS Management section: Look for an option like “DNS Settings” or “DNS Management.”

• Add a new TXT record: You will add a new DNS record for your domain. Choose “TXT” as the record type.

• Enter the details for your DMARC record:

• Name/Host: Usually, this is _dmarc.yourdomain.com. Replace “yourdomain.com” with your actual domain name.
• Value: This is the content of your DMARC record. A basic DMARC record looks like this:

v=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com; ruf=mailto:dmarc-reports@yourdomain.com; pct=100;

v=DMARC1: Specifies the DMARC protocol version.

p=none: This is the policy that tells email servers what to do with emails that fail SPF or DKIM checks. “None” means do nothing, but you can change this to “quarantine” (send to spam) or “reject” (block the email) once you’re confident everything is working.

rua=mailto

@yourdomain.com: This is where aggregate reports (summary reports) will be sent. Replace with your email address.

ruf=mailto

@yourdomain.com: This is where forensic reports (detailed reports) will be sent. Replace with your email address.

pct=100: This tells servers to apply the policy to 100% of the emails. You can adjust this to a lower percentage if you want to test the waters first.

• Save your DNS changes: Once you’ve entered all the details, save the new record.

Step 3: Validate Your DMARC Record

After setting up your DMARC record, it’s important to check that it’s working correctly:

• Use a DMARC checker tool: Several online tools can validate your DMARC setup. Just search for “DMARC record checker,” and you’ll find options like MXToolbox, DMARC Analyzer, or DMARCian.
• Enter your domain: The tool will check if your DMARC record is correctly set up and will give you feedback on any errors.

Step 4: Monitor DMARC Reports

Once your DMARC record is live, you’ll start receiving reports that show you how your domain is being used. These reports will help you:

• Identify unauthorized email activities.
• Fine-tune your DMARC policy: Once you’re confident everything is set up correctly, you can change your DMARC policy from p=none to p=quarantine or p=reject to increase protection.

Step 5: Adjust Your Policy for Maximum Protection

After monitoring your reports for a while and confirming that legitimate emails are passing through DMARC checks without issues, you can increase the strictness of your policy:

• Change p=none to p=quarantine: This will send emails that fail DMARC to the recipient’s spam folder.
• Change p=quarantine to p=reject: This will block emails that fail DMARC entirely.

Common Pitfalls and How to Avoid Them

• Not having SPF or DKIM properly set up: DMARC relies on these protocols. Make sure they are configured correctly before implementing DMARC.
• Skipping the monitoring phase: Don’t rush to enforce a strict policy (like p=reject) without monitoring your reports first. You might accidentally block legitimate emails.
• Forgetting to update the email addresses in the DMARC record: Make sure the rua and ruf fields point to email addresses where you can receive reports.

Conclusion

Fixing the “No DMARC record found” issue is an essential step to protect your domain from email fraud and improve your email deliverability. By following this guide, you can create and implement a DMARC record that suits your needs, monitor its effectiveness, and gradually enforce stricter policies to ensure your domain is safe and secure. Remember, the key to a successful DMARC implementation is to take it step by step and monitor the results carefully.
