Dmarc Records

Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol that is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing. The purpose and primary outcome of implementing DMARC is to protect a domain from being used in business email compromise attacks, phishing emails, email scams, and other cyber threat activities. 

Develop a DMARC Policy

Before you add a DMARC record, decide on the policy you want to enforce. There are three types of DMARC policies:

Create Your DMARC Record

A DMARC record is a TXT record in your DNS that looks something like this:

v=DMARC1; p=none; rua=mailto:dmarc-@example.com; ruf=mailto:dmarc-failures@example.com; fo=1;

This example tells email servers that:

 Access Your Domain's DNS Settings

Navigate to DNS Management

Add the DMARC Record

Save the Record

Test Your DMARC Record

Setting up DMARC is a proactive measure against email spoofing and phishing—it's not an instant fix, but it's an important part of a comprehensive email security strategy. Keep tweaking and monitoring, and you'll be on the right track to keeping your domain's reputation clean and your emails landing where they should.
