Instructions

Open the live workbench
Use the runtime panel to inspect the rendered evidence page, then download the .eml if you want to validate the raw message yourself.
Triaging headers
Compare the visible sender to the underlying path the message took. Identify the first clue that says this is not normal vendor mail.
Make the analyst call
Decide whether the message should be delivered, quarantined, or escalated. Your answer should reflect the evidence, not just suspicion.
