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 1 - the rua and ruf settings must be a valid email on the mail account on the same domain. The dmarc@yourdomain.com ones are merely an example.
IMPORTANT NOTE 2: - the email address you use for dmarc reports will receive reports on a daily basis, so we recommend you set up a filter in your email to handle them or you will/might receive 10's of reports daily if you send out emails on a regular basis.
Alternatively, if you are a client of JUCRA we can manage this for you. See this kb here.
v=DMARC1;p=reject;sp=none;adkim=r;aspf=r;pct=100;fo=1;rf=afrf;ri=86400;rua=mailto:dmarc@yourdomain.com;ruf=mailto:dmarc@yourdomain.com
3. In Cpanel DNS 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
