This guide will explain how to add a default DMARC record into DNS, DMARC records are used to help monitor for email spoofing on a domain, they can also be used by spam filters whether emails land in spam or discarded
The DMARC record added in this guide will have no policy, if spoofing has been reported on a domain it is advisable to have a stricter DMARC policy, but as a part of setting up DNS it is advisable to add a default DMARC record. The DMARC record in this guide will not negatively impact email deliverability
TL;DR DMARC records can be added as TXT records in cPanel via cPanel > Zone Editor > Manage > Add DMARC Record > Save Record
