Trace Phishing Email Origin

I have been receiving phishing-style messages in my Gmail inbox and I want to know exactly where they are coming from. Specifically, I need a clear breakdown of both the sender’s IP address and the corresponding geographical location for each of the emails I forward to you.

These messages appear to be crafted to look legitimate, so a simple header glance is not enough—I’m after a thorough forensic review. Please use whatever combination of header analysis, IP-lookup, reverse DNS, and open-source intelligence tools you find most accurate, but document every step so I can follow the chain of evidence.

Deliverables
• A concise report for every email I provide, listing:
– Extracted sender IP address (with evidence from the raw header)
– Mapped city, region, and country of origin
– Any intermediate relays or spoofing indicators uncovered
• A brief explanation (plain language) of the techniques used so I can repeat the process in future
• Recommended next steps to block or filter similar threats and keep my Gmail account secure

I will forward the suspicious messages once we start; please keep all findings confidential and return results in an editable format (PDF or DOCX preferred).
