Why You Need a DMARC Record

DMARC (Domain-based Message Authentication, Reporting and Conformance) is a security protocol that gives email domain owners the power to protect their domain from email spoofing and ensure that their email is being delivered to their recipients’ inbox. It is essential to create a DMARC record because most cyber attackers use email spoofing to send emails as someone else. DMARC aims to combat email spoofing by authenticating emails sent from your domain and blocking unauthenticated emails that appear to come from your domain.

Creating Your DMARC Record

The first step in creating your DMARC record is to determine whether you have an existing DMARC record. You might already have a DMARC record if you have set up an SPF (Sender Policy Framework) and/or DKIM (DomainKeys Identified Mail). If you don’t have a DMARC record yet, you can create one by following these steps:

Step 1: Log in to your DNS provider. This may be the same company that hosts your website or email.

Step 2: Navigate to the DNS management section of your account.

Step 3: Create a new TXT record for your domain and include the following information:

v=DMARC1; p=quarantine; ruf=mailto:[email protected]; rua=mailto:[email protected];

In the above example, the “p” indicates the policy to apply. “Quarantine” means that the emails that fail authentication will still be delivered to the recipient, but they will be marked as spam. You can also set the policy to “reject”, which will reject emails that fail authentication entirely.

The “ruf” and “rua” fields are reporting mechanisms that allow you to receive DMARC reports when there is an issue with your email authentication. “ruf” refers to forensic reports, which provide detailed information about individual emails that fail authentication. “rua” refers to aggregate reports, which summarize authentication results for your domain.

Testing Your DMARC Record

Once you have created your DMARC record, the next step is to test it to ensure that it is working correctly. You can test your DMARC record by visiting https://dmarcian.com/dmarc-inspector/ and entering your domain name.

If you see a green checkmark, it means that your DMARC record is working correctly, and emails sent from your domain are being authenticated. If you see a red X, it means that your DMARC record has not been set up correctly, and you should check your DNS settings.

Monitoring Your DMARC Record

After you have created your DMARC record and tested it, the next step is to monitor it regularly to ensure that it is working correctly. You can monitor your DMARC record by subscribing to reporting services that provide real-time DMARC data. These services will provide you with detailed information about your email authentication status and how your emails are being received by your recipients.
