DMARC Reports Analysis

DMARC stands for Domain-based Message Authentication, Reporting, and Conformance. It is an email authentication protocol that uses SPF and DKIM to verify the authenticity of emails. DMARC allows email senders to publish policies in their DNS records that specify how email receivers should handle emails that fail authentication checks. It provides a mechanism for senders to receive reports from receivers about email delivery and authentication.

The primary benefit of using DMARC is that it helps prevent email spoofing and phishing attacks by verifying the authenticity of email messages. DMARC also provides visibility into email delivery and allows senders to monitor and analyze email authentication data. This can help organizations improve their email deliverability and protect their brand reputation.

To apply DMARC to your domain, you must create a DMARC record in your DNS. This record will specify how receivers should handle emails that fail SPF and DKIM checks. You can also specify that receivers send reports back to you about email delivery and authentication. It is recommended to start with a DMARC policy set to "none" to monitor email delivery and authentication before enforcing stricter policies.

It is recommended to examine DMARC reports regularly to monitor email delivery and authentication. Look for patterns in the data, such as which IP addresses are sending an email.
