Multi-Step Inbound Security Auditor

This workflow helps anyone who needs to check the security of incoming emails using IP reputation and email authentication protocols. This workflow gets email header data, then checks it in two ways. First, it looks at IP addresses for potential fraud. Second, it checks email authentication like SPF, DKIM, and DMARC. Then, it combines all this information and sends back a security report. This workflow starts when a webhook receives data. You must replace the API key in the "IP Quality Score" node with your own key. No other setup is needed, but you can change the webhook to an "Execute Workflow Trigger" to use it as part of a larger process. You need an IP Quality Score API key for IP reputation checks. You also need an n8n environment to run this workflow. You can change how the workflow extracts and analyzes email headers. You can also adjust the rules for fraud scoring and how the final report is created. For example, change the fraud score thresholds in the "Fraud Score" node or the authentication checks in the "SPF/DKIM/DMARC from authentication-results" node. Key Technologies: n8n,IP Quality Score API,IP-API (Geolocation),JavaScript (for data processing) Automation Value: - Automatically analyzes email headers upon receipt. - Reduces manual effort in checking email security and IP reputation. - Provides a quick security overview of incoming emails. - Helps identify potential spam or phishing attempts early. - Integrates external security services for comprehensive checks. Best Practices: Always configure API keys securely, preferably using environment variables or n8n credentials, instead of hardcoding them. Ensure reliable error handling for API calls (e.g., rate limits, server errors) to make workflows more reliable. Use clear and consistent naming for nodes to improve workflow readability and maintenance. Regularly review and update "Sticky Notes" to keep documentation accurate and helpful. Consider using "Try/Catch" blocks for code nodes to manage errors gracefully and prevent workflow failures.
