What is a DMARC Policy and Policy Options? | EasyDMARC

DMARC Policy

A DMARC policy is a set of rules that domain owners create to tell email servers how to handle emails that fail authentication checks like SPF and DKIM. It helps prevent email spoofing, phishing, and domain misuse by ensuring only authorized emails can be sent from a domain.

 

The policy allows domain owners to specify how to treat emails that fail authentication, ensuring better security and trust. By implementing a DMARC policy, businesses protect their brand reputation and secure email communication from cyber threats. 

What Are The Different DMARC Policy Options?

None: This option is used for monitoring only. It does not impact email delivery but collects data on failed authentication attempts, helping businesses understand how their email security is performing.
Quarantine: Emails that fail DMARC checks are sent to the spam or junk folder. This option enhances security by isolating suspicious emails without rejecting them outright, offering a balance between security and deliverability.
Reject: The strictest policy, where emails that fail authentication are completely rejected. This provides maximum protection against spoofing and phishing but could potentially impact legitimate email delivery if not properly configured.

How to Set Up a DMARC Policy

Setting up a DMARC policy involves a few key steps to ensure your email domain is protected. Here’s a simple guide:

Create a DMARC Record: Start by adding a DMARC record to your domain’s DNS settings. This record defines your policy and instructs email servers on how to handle authentication failures.
Choose the Right Policy Option: Based on your organization’s needs, choose either None, Quarantine, or Reject for a policy. Begin with "None" for monitoring and, as you refine your strategy, move to "Quarantine" or "Reject" for stronger protection.
Monitor and Adjust: Regularly check your DMARC reports to track how your emails are being authenticated. Over time, adjust your policy to improve security, gradually moving to "Reject" for maximum protection.

Benefits of Implementing a DMARC Policy

Implementing a DMARC policy helps protect your brand by preventing email spoofing and phishing, 

ensuring that attackers cannot impersonate your domain. It also improves email deliverability by ensuring 

legitimate emails are more likely to reach inboxes, fostering trust with recipients.

 

DMARC enhances email security by reducing the risk of phishing and business email compromise, 

preventing unauthorized emails from entering circulation. It ensures compliance with email authentication 

standards, aligning your business with best practices and securing communications.
