CyberGuardians Express: Analyzing Email Headers in Gmail & MXToolbox

from CyberGuardians Hosted by Marcellus

In this CyberGuardians Express episode, we walk through how to analyze email headers using Gmail and MXToolbox to detect phishing and spoofed emails. You’ll learn how to open Gmail’s “Show original” view, extract the raw email header, and use MXToolbox to convert that data into a human-readable report. We also break down what SPF, DKIM, and DMARC actually mean in plain English so you can understand what’s protecting your inbox and what attackers try to bypass. This episode shows you how to: Navigate Gmail to view full email headers Identify phishing red flags hidden in email metadata Understand SPF, DKIM, and DMARC without technical jargon Use MXToolbox to verify sender IPs, domains, and blacklists If you’ve ever wondered how to tell whether an email is real or fake beyond just looking at the sender name, this episode gives you the exact tools and workflow security professionals use.
