Domain-based Message Authentication, Reporting and Conformance (DMARC) is an email authentication protocol. It is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing .
Demarcation point is sometimes abbreviated as demarc, DMARC, or similar. The term MPOE ( minimum or main point of entry ) is synonymous, with the added implication that it occurs as soon as possible upon entering the customer premises.
DMARC provides the ability for an organisation to publish a policy that specifies which mechanism (DKIM, SPF, or both) is employed when sending email from that domain; how to check the From: field presented to end users; how the receiver should deal with failures—and a reporting mechanism for actions performed under those policies.

However, a strict DMARC policy may block legitimate emails sent through a mailing list or forwarder, as the DKIM signature will be invalidated if the message is modified, such as by adding a subject tag or footer, and the SPF check will either fail (if the forwarder didn't change the bounce address) or be aligned with the mailing list domain ...
