Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol. It 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 email, email scams and other cyber threat activities.
DMARC is not an essential DNS record for mail delivery -- it mostly is to prevent spoofing of your domain. For proper mail delivery, you will need an A record and an MX record; an SPF TXT record is also highly recommended. And any more, a PTR (reverse DNS) record is essential for credibility with other mail servers. This is put in place by your hosting provider or ISP, whoever controls the IP space you use.
