DMARC stands for Domain-based Message Authentication, Reporting & Conformance. DMARC is an email authentication protocol designed to give domain name owners the ability to protect their domain name from unauthorized use. DNProtect believes it is important to set up DMARC on a domain name to help protect from business email compromise attacks, phishing emails, email scams and other cyber threat activities. In order to set up DMARC, you need to talk with your website host. For more information, see DMARC.org or Wikipedia https://en.wikipedia.org/wiki/DMARC
