Email authentication is one of the most useful and most misunderstood parts of suspicious-message review. It gives defenders evidence about how a message moved, which domain authorized parts of the sending path, and whether the visible sender aligns with authenticated mail. It does not promise that a message is harmless. A message can pass authentication and still ask for an unsafe business action. A message can fail one check because of forwarding or misconfiguration and still be ordinary.

Phishing and business email compromise are easy to describe poorly. A message arrives, something feels wrong, and the room begins arguing about whether it is fake. Good defensive triage slows that moment down. The first question is not whether the message is malicious. The first question is what the message is asking a person or system to do, what evidence supports the request, and what business process would normally confirm it.
