There are two main types of DMARC reports: aggregate reports and failure (forensic) reports. Aggregate reports provide a summary of the messages that have been sent from a domain and how they have fared in DMARC evaluation. They typically include information such as the number of messages that have passed or failed DMARC evaluation, the percentage of messages that have passed or failed, and the IP addresses of the sending servers. Aggregate reports are useful for domain owners who want to get a high-level overview of how their domain is being used and how well it is protected by DMARC. They can help domain owners to identify trends and patterns in their email traffic and to identify any potential issues that may need to be addressed, including SPF and DKIM results. Failure (forensic) reports, on the other hand, provide a detailed breakdown of individual messages that have failed DMARC evaluation. They typically include information such as the headers of the message, the SPF and DKIM results, and any other relevant data.
