How does it protect your domain from being spoofed by phishing scam emails?

DMARC is an acronym for "Domain-based Message Authentication, Reporting & Conformance". It is a security and email authentication protocol that allows businesses to belgium phone number list protect their domains from being spoofed by phishing scam emails. It is also used by email service providers and Internet service providers to detect and prevent fraud.

If you haven't heard of it, don't worry, it's actually pretty easy to understand. DMARC is an email authentication standard that helps you prevent spoofing, phishing, and other email-based attacks. What it does is allow you to define a policy for how your domain should handle emails with invalid sender addresses.

The first step to setting up DMARC is to register your domain with SPF so that you can control which IP addresses can send email on behalf of your company. You will also need to set up DKIM and start reporting email abuse through spam reporting or abuse reporting.

When an ISP receives an email with a DKIM record, they check the sender's domain against their own DNS records. If there is no SPF record, or if they don't match what they have on file, they reject the email as it could be spam or spoofed content from another source (like a phishing attack).
