Understanding DMARC
Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that helps protect your brand reputation and customers from email phishing and spoofing. Email phishing is a fraudulent attempt by malicious actors to obtain sensitive information or data by posing as a reputable source through email. Spoofing is when a hacker assumes the identity of a genuine sender to trick victims into opening and acting on an email.
Setting Up DMARC for Your Domain
To set up DMARC, you must first verify that the domain authority is under your control. Domain authority is the ability to control the domain name system records for your domain.
The first step in setting up DMARC is to publish a DMARC record in the DNS. This record sets the policy for email receivers to follow when they encounter an email message from your domain. You can do this by adding a new TXT record to your domain’s DNS, which contains the DMARC policy settings. Make sure to specify the subdomains you want to include in your DMARC policy.
You can set three levels of DMARC policy: None, Quarantine, and Reject.
It is recommended to start with the “None” policy before moving to “Quarantine” and “Reject” policies to minimize the impact on your email deliverability.
DMARC Reporting and Monitoring
DMARC reporting is a critical feature that helps you monitor and analyze your email authentication status. It provides valuable insights into the effectiveness of your DMARC policy and helps identify any unauthorized use of your domain name and email servers.
