DMARC stands for “Domain-based Message Authentication, Reporting & Conformance”, is an email authentication, policy, and reporting protocol. It builds on the widely deployed SPF and DKIM protocols, adding linkage to the author (“From:”) domain name, published policies for recipient handling of authentication failures, and reporting from receivers to senders, to improve and monitor protection of the domain from fraudulent email.
DMARC records are created at DNS zone level so you will need to add the following details to the dns for your domain.
1. Create a TXT record with value: _DMARC
2. Add the following line as the TXT value.
"v=DMARC1; p=none; fo=1"3. Your dns should look something like this:
4. You can then verify the dmarc settings exists by doing a lookup.
