How to read a DMARC report
Blog post from Resend
DMARC, which stands for Domain-based Message Authentication, Reporting & Conformance, is a crucial protocol for preventing email spoofing by providing insights into email authentication. It operates as a DNS record that enhances domain security and delivers detailed reports about email activity, allowing domain owners to monitor and protect against unauthorized use. DMARC reports come in two forms: forensic (RUF) and aggregate (RUA), with RUA being recommended for regular monitoring due to its comprehensive overview of email authentication patterns. These reports help identify authentication gaps, sending patterns, and potential security threats by detailing the status of each email against SPF and DKIM checks. Reading these reports requires understanding XML data, which can illuminate email handling outcomes like delivery, spam, or rejection based on the DMARC policy. Analyzing these patterns aids in taking corrective actions to improve email deliverability and security, making DMARC a pivotal part of any email strategy.
