DMARC Record Lookup
What is DMARC?
DMARC (Domain-based Message Authentication, Reporting and Conformance), is an email authentication standard, policy, and reporting protocol. It builds on the widely deployed SPF & DKIM protocols and is the only way for email senders to tell email receivers that the emails they are sending are truly from them. Using DMARC enables senders to publish a policy on how email servers should react on inauthentic messages.
