How DMARC Serves as the Ultimate Stoplight for Email Traffic

When a community agrees to govern traffic with signals, we see traffic stop and go at safe intervals. Acceptance of traffic signals is a convention that affects safety for three reasons:

• The community knows the meaning.
• The community accepts the meaning.
• The community acts on the meaning.

The DMARC (Domain-based Message Authentication Reporting and Conformance) policy is an email traffic signal that allows us to stop fraudsters who abuse domains to impersonate you, your partners, and your customers.
