Automate Gmail Email Header Analysis for Enhanced Security & Insights
detail.loadingPreview
This n8n workflow automates the extraction and analysis of Gmail email headers, focusing on identifying original IP addresses and authentication results for enhanced email security and sender verification.
About This Workflow
Gain deeper insights into your incoming emails with this powerful n8n workflow. By automatically triggering on new Gmail messages, it meticulously extracts and parses email headers. The workflow is designed to identify the original IP address of the sender, bypassing proxies and local IPs, and then leverages external APIs like IP Quality Score and ip-api.com for reputation and geolocation analysis. It also checks for crucial authentication headers like 'Authentication-Results' and 'Received-SPF' to verify sender legitimacy and detect potential spoofing. This comprehensive analysis empowers you to build more robust email security protocols and understand the origin of your communications.
Key Features
- Automated Gmail Trigger: Initiates the workflow upon receiving new emails.
- Original IP Extraction: Identifies the sender's true IP address, ignoring internal or proxy IPs.
- IP Reputation & Geolocation: Utilizes IP Quality Score and ip-api.com for detailed IP analysis.
- Authentication Header Analysis: Detects and processes 'Authentication-Results' and 'Received-SPF' headers.
- Customizable Logic: Built with n8n's robust conditional nodes for flexible rule creation.
How To Use
- Connect Gmail: Set up the 'Gmail Trigger' node and authenticate with your Gmail account. Ensure it's enabled.
- Extract Headers: The 'Gmail - Extract Received Headers' node automatically pulls relevant header information from the trigger.
- Extract Original IP: Configure the 'Gmail - Extract Original From IP' node to isolate the sender's original IP address from the headers.
- Conditional IP Check: Use the 'Gmail - Original IP Found?' node to branch your workflow based on whether a valid original IP was detected.
- IP Analysis (if IP found): If an IP is found, connect to 'Gmail - Query IP Quality Score API' and 'Gmail - Query IP API' to gather reputation and location data.
- Authentication Checks: Utilize the 'Gmail - Authentication-Results Header?' and 'Gmail - Received-SPF Header?' nodes to check for specific authentication results. You may need to further process these results using additional code nodes depending on your specific needs.
- Further Processing: Connect subsequent nodes to process the gathered IP and authentication data for actions like logging, flagging, or routing emails.
