DMARC policy management

Setting up and maintaining email security for an organization can sometimes feel like navigating a labyrinth of spam, phishing, and cyber threats.

Maybe you even feel a bit like the heroes of a heroic fantasy novel embarking on an epic quest. But fear not! Libraesva is your Gandalf, and we’re ready to guide you through the challenging DMARC landscape.

In this article, we’ll unravel 10 DMARC policy management dos and don’ts.

Ready for an email security adventure? Let’s dive into the world of DMARC policy management best practices.

1. Do Understand DMARC’s Purpose 

DMARC is not just another security measure; it’s an important authentication protocol that enables domain owners to protect their company and its employees from malicious actors. It authenticates the sender’s identity and instructs email receivers on handling unauthorized messages.

2. Don’t Rush the Journey 

One common mistake when implementing DMARC is rushing the process. While solutions like Libraesva’s LetsDMARC can be implemented very quickly, it’s still a good idea to take your time to plan and configure your DMARC policy effectively. Set up appropriate DNS records, collect and analyze DMARC reports, and gradually move from a ‘none’ policy to ‘quarantine’ or ‘reject’ as you gain confidence.

3. Don’t Neglect SPF and DKIM

DMARC leverages DNS and uses Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) open protocols to authenticate emails. Ensure that your SPF and DKIM records are correctly configured before implementing DMARC. LetsDMARC simplifies the monitoring of SPF and DKIM alignment, helping you pinpoint and rectify issues quickly.

4. Do Start with a “None” Policy

When setting up your DMARC policy, it’s wise to begin with a ‘none’ policy (p=none). This policy allows you to gather reports and analyze the results without affecting the delivery of your emails. It’s a crucial first step toward understanding your email ecosystem and identifying unauthorized senders.

5. Do Monitor DMARC Reports

LetsDMARC simplifies the process of collecting and analyzing DMARC reports. Regularly review these reports to identify sources of email fraud and phishing attempts. They are a goldmine of information, providing the information you need to create the most secure DMARC policy possible.

6. Do Keep Your Records Updated 

Maintaining current SPF and DKIM records is essential for a successful DMARC policy. As your company evolves and new email services are introduced, adjust your DNS records accordingly. LetsDMARC can assist you in monitoring these records to help you stay current on any necessary updates.

7. Don’t Ignore False Positives & Negatives

False positives (legitimate emails incorrectly identified as fraudulent) and false negatives (fraudulent emails that are missed) are common issues in DMARC management. Monitor these occurrences and adjust your DMARC policy to address any gaps. LetsDMARC provides insights into these issues, making it easier to address them quickly and efficiently.

8. Don’t Set It and Forget It 

DMARC policy management is an ongoing process. As your email ecosystem evolves, so should your DMARC policy. Regularly review and update your policy to adapt to changing circumstances to stay ahead of emerging threats.
