Frequently Asked Questions

Frequently Asked Questions

What is DMARC?

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that helps prevent email spoofing and phishing attacks. It works by verifying that emails are sent from authorized senders and provides a mechanism for reporting any suspicious activity.

Why is DMARC important for email security?

DMARC plays a crucial role in email security by ensuring that only legitimate emails reach recipients. It helps prevent spam, phishing, and other malicious activities by verifying the sender's identity and authenticity.

How does DMARC work?

DMARC works by verifying the sender's identity using SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records. It then enforces policies based on the results of these checks, such as allowing, quarantining, or rejecting emails that fail authentication.

What are the benefits of implementing DMARC?

Implementing DMARC provides several benefits, including improved email deliverability, reduced spam and phishing attacks, enhanced brand reputation, and increased user trust.

Where can I find official DMARC documentation?

The most authoritative sources for DMARC information are the official specifications and documents published by the Internet Engineering Task Force (IETF), such as RFC 7489 and RFC 8601.
