Implement DMARC in 5 Simple Steps to Protect Your Email and Boost Your Security

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a type of email protocol that uses SPF (Sender Policy Framework) and DKIM (Domain Keys Identified Mail). It’s a technical standard (RFC7489) meant to shield legitimate businesses from spam, phishing, and other forms of email abuse by preventing third parties from using their domains without permission.

Should you implement DMARC?

Whether or not you should implement DMARC depends on your specific needs and circumstances. Here are a few key considerations to help you decide if DMARC is right for you:

Do you want to protect your domain from spam, phishing, and other types of email fraud? DMARC helps to verify the authenticity of emails sent from your domain, which can reduce the risk of these types of threats.
Do you want to improve the deliverability of your emails? DMARC can help to ensure that your emails are properly authenticated, which can reduce the risk of them being marked as spam or rejected by email servers.
Do you want to protect your brand reputation? DMARC can help to prevent unauthorized use of your domain, which can protect your brand’s reputation and prevent damage to your business.
Do you want to improve your email security? DMARC provides detailed reports that can help you identify and address potential security issues or problems.

In addition, DMARC provides detailed reports that can help you identify and address any potential security issues or problems. Overall, implementing DMARC is a simple and effective way to enhance the security of your email and protect your domain from potential threats.

It needs some preliminary work before you implement DMARC, including, of course, corporate consent, because it covers the entire company.

Steps to implement DMARC

Step 1: Publish a DMARC record in your DNS records

The first step to implementing DMARC is to publish a DMARC record in your domain’s DNS (Domain Name System) records. This record specifies the policies you want to apply to emails sent from your domain, as well as the email address where you want to receive DMARC reports.

To create a DMARC record, you’ll need to use a text editor to create a simple text file with your DMARC policies and settings, and then upload this file to your DNS server or you can use a DMARC record generator.

Step 2: Configure your email servers

Once you have your DMARC record set up, you’ll need to ensure that all of your email servers are properly configured to support DMARC. This includes setting up DKIM and SPF to authenticate your emails. SPF is a DNS-based authentication protocol that verifies that an email was sent from an authorized server, while DKIM uses digital signatures to verify the authenticity of an email’s content.

Step 3: Monitor your DMARC reports

After you have your DMARC record and email servers configured, you can begin to monitor your DMARC reports. These reports will provide information about how well your DMARC policies are being enforced, and will help you identify any potential issues or problems. You can view your DMARC reports either by logging in to your DMARC provider’s dashboard or by checking the email address specified in your DMARC record.

Step 4: Adjust your DMARC policies as needed

As you monitor your DMARC reports, you may need to make adjustments to your DMARC policies to ensure that they are effective. This may involve adjusting your SPF and DKIM configurations, or making changes to your DMARC record. For example, you may need to add or remove domains or IP addresses from your SPF or DKIM records, or adjust your DMARC policy settings to allow or block certain types of emails.

Step 5: Regularly review and update your DMARC policies

Finally, it’s important to regularly review and update your DMARC policies as needed. This will help to ensure that your DMARC check is effective and that your email security is up to date. You may want to schedule regular reviews of your DMARC policies, perhaps once a month or once a quarter, to ensure that everything is in order.

Deploying DMARC calls for some experience with DNS and email server configuration. If you don’t feel confident handling DMARC policy implementation and upkeep on your own, it’s a good idea to consult with an experienced IT professional or service provider.

How hard is it to implement DMARC?

DMARC requires a certain level of technical expertise and familiarity with DNS and email server configuration. Technical difficulty is not hard but you might need experts with experience since wrong implementation can cause email delivery loss.

Where do I setup DMARC at?

To set up DMARC on your domain, you’ll need to publish a DMARC record in your domain’s DNS records. DNS records are the publicly available records that contain information about your domain and its associated servers. By publishing a DMARC record in your DNS records, you can specify the policies you want to apply to emails sent from your domain, as well as the email address where you want to receive DMARC reports.
This is typically done at your registrar or hosting providers like Godaddy, Cloudflare etc.

How long does it take to implement DMARC?

The amount of time it takes to implement DMARC on your domain will depend on several factors, including your technical expertise and the complexity of your email infrastructure. In general, however, you can expect the process to take a few hours to a few days, depending on the steps involved.

Conclusion

Implementing DMARC is an important step for protecting your email and boosting your security. By following these five simple steps, you can quickly and easily set up DMARC on your domain and start benefiting from the enhanced email security it provides.
