What is DMARC?

The DMARC risk vector determines whether domains have a Domain-based Message Authentication, Reporting and Conformance (DMARC) policy or not and evaluates how effective it is at ensuring only verified senders are able to use this domain for email.

DMARC Record

The DMARC text resource. It is published in the DNS on the subject domain and consists of a list of semicolon-separated DMARC tags.

DMARC Tags

DMARC tags are used in a DMARC record to define various aspects of a DMARC implementation, such as policy, aggregate report email URI, forensic report email URI, and more. Each tag has a value which defines a certain aspect of DMARC.

See DMARCLY, “What are DMARC Tags: DMARC Tags Explained” for available tags.

Domain-based Message Authentication, Reporting and Conformance (DMARC)

DMARC provides a measure of protection against spoofing, authenticates that the sender of an email is legitimately authorized to send email on the company’s behalf, and tells the email receiver what to do with email messages that fail DMARC authentication.
