DMARC: Secure Your Email & Protect from Spammers & Sophisticated Spoofing Attackers

Written by Scott Leahy | Aug 22, 2023 6:15:40 PM

Email authentication is critical in today's digital landscape, as it helps protect against fraudulent and malicious email traffic. One key aspect of email authentication is DMARC (Domain-Based Message Authentication, Reporting, and Conformance.) 

What is DMARC?

DMARC is a technical standard that defines how email servers should handle messages that fail SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) checks. By implementing a DMARC policy, you can help ensure that only authorized email is sent from your domain, helping to protect your brand and your customers. 

How does it work?

Technically speaking, DMARC leverages SPF and DKIM to prevent phishing and spoofing attacks by providing a way for receivers to reject emails from unknown sources. The protocol defines guidelines to follow if a message fails authentication. DKIM protocol allows you to add a signature to your message with a private and public key used by the receiving server to validate the message’s source.
