Email source code

As explained in AI for Everyday IT

Email source code is the raw structured content of an email message, including its headers, body markup, and embedded metadata.

Email source code is the jumble of headers and message content behind an email. It can help investigate suspicious messages, especially those requesting clicks or sensitive information. section 7.1.3

In Outlook for Mac, right-click the message and choose View Source. In Outlook for PC, open the message, choose File, and select Properties. Copy the displayed source and headers into an AI service; you do not need to understand every line. section 7.1.3

Phishing check

Paste the source content into M365 Copilot and ask it to determine whether the email is a phishing attempt. Its analysis can identify authentication failures involving SPF, DKIM, and DMARC. section 7.1.3

What it assumes

Assumes access to an email client and AI service while teaching that source text need not be understood line by line.

What you can do after

Diagnose possible phishing attempts by retrieving email source and asking an AI service to inspect it.

How it connects

Connects email headers with phishing, SPF, DKIM, DMARC, and M365 Copilot.
