DMARC stands for “Domain-based Message Authentication, Reporting & Conformance”, which 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 the protection of the domain from fraudulent email.
DMARC records are created at the 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.
IMPORTANT NOTE - the rua and ruf settings must be a valid email on the mail account on the same domain. The servers@jucra.com ones are merely an example.
"v=DMARC1;p=reject;sp=none;adkim=r;aspf=r;pct=100;fo=1;rf=afrf;ri=86400;rua=mailto:servers@jucra.com;ruf=mailto:servers@jucra.com"
3. In Cpanel you can configure the DMARC or raw settings like this in the DNS manager.
4. You can then verify the dmarc settings exists by doing a lookup on www.dnswatch.info or using www.dmarcian.com
