Email Header Analysis Workflow for Spam & Authentication Check

This n8n workflow automates the analysis of incoming email headers to evaluate their legitimacy and security. It begins by triggering on new emails received in Outlook, then retrieves detailed email headers through Microsoft Graph API. The process extracts and filters ‘Received’ headers to identify the originating IP address, which is then analyzed for reputation and geographic data via third-party APIs. Additionally, the workflow checks for key authentication results like SPF, DKIM, and DMARC by parsing respective headers. It consolidates all findings to assess whether the email is potentially spam or a legitimate message, providing a comprehensive overview of email authenticity and sender reputation. This workflow is particularly useful for email security monitoring, spam detection, and automated reporting within organizational cybersecurity measures.
