DMARC Email Process

Visual Concept Illustration

What Needed to Be Explained

When Domain-Based Message Authentication, Reporting, and Conformance (DMARC) was implemented more broadly across the Internet, college IT needed an easy way to explain it to faculty, staff, and students. DMARC gives email admin a way to defend against spoofing (fraudulent emails trying to trick people into giving away their passwords, downloading viruses, etc.). It verifies whether an email message actually came from the place it was supposedly sent from. If the originating domain and the from address don’t match, it’s possible that a message will be rejected or quarantined. Rejected messages will bounce back to the sender, but when a message is quarantined, nobody (not the sender, nor the recipient) is notified.
