Email - Header Analyzer

What is "Email - Header Analyzer"?

Email - Header Analyzer is a lightweight PowerShell script designed to analyze Office 365 email headers and display the following information:

• SPF - pass / fail / softfail / neutral / Unknown
• DKIM - pass / fail / none / Unknown
• DMARC - Compliant / Non-Compliant
• Sender (Envelope/Return Path) - Email Address / NOT FOUND & Likely Spoofed or Spam
• Sender (Header/Client Display) Email Address / NOT FOUND & Likely Spoofed or Spam
• O365 Classification: Internal / Internal (Partner) / External
• Message Source: Internal / External

Why create this and have a compiled version?

Question: Why have a mini program for something MxToolbox can do for free?

• I wanted a lightweight, fast program to pin to my taskbar for easy access while limiting the exposure of personal data.

Question: How was it compiled?

• It was compiled with PS2EXE using the following command:
• Invoke-PS2EXE -inputFile '.\O365-EmailHeaderAnalyzer.ps1' -outputFile '.\O365-EmailHeaderAnalyzer.exe' -iconFile '.\email_icon.ico' -noConsole -noOutput
• Source: PS2EXE GitHub

Usage

1. Run either Message - Header Analyzer.ps1 or Message - Header Analyzer.exe.
2. Set your internal domain and click Save.
3. Paste message headers into the Message Details textbox.
