DMARC Lookup
This test will list DNS DMARC-Records for a domain. Domain-based Message Authentication, Reporting, and Conformance (DMARC) is a mechanism for policy distribution by which an organization that is the originator of an email can communicate domain-level policies and preferences for message validation, disposition, and reporting. The DNS DMARC-Record lookup is done directly against the domain's authoritative name server, so changes to DNS DMARC-Records should show up instantly.
