## **Evaluate SPF, DKIM, and DMARC Compliance**

This section focuses on detailed analysis and validation of SPF, DKIM, and DMARC headers. Each authentication mechanism is evaluated to determine its status, providing critical insights into the email’s legitimacy and adherence to security protocols.

The workflow begins with the `Received-SPF Header?` node, which checks if the "Received-SPF" header exists. If found, the workflow proceeds to the `Extract Received-SPF Header` node to isolate the SPF validation results. These results are aggregated and analyzed using the `Aggregate Received-SPF Headers` node, with the final outcome recorded by the `Set SPF Value` node. If no SPF header is found, the workflow instead records this absence using the `No SPF Found` node.

The `DKIM-Signature Header?` node performs a similar function for DKIM validation, checking for the presence of a DKIM signature. If the header is found, the `DKIM Signature Found` node confirms its presence, while the `No DKIM Signature Found` node handles its absence.

The `DMARC Header?` node checks for the presence of a DMARC header, indicating compliance with the domain’s published DMARC policy. If present, the workflow extracts and evaluates it via the `Extract DMARC Header` and `Set DMARC Value` nodes. If the header is missing, the `No DMARC Header` node records this information.

By systematically evaluating these headers, the workflow provides a comprehensive understanding of the email's authentication status. This granular analysis strengthens email security by detecting potential spoofing or misconfigurations in the sender’s authentication setup.
