Introduction

Email headers contain crucial technical information about message routing, authentication, and delivery that can be essential for troubleshooting delivery issues, verifying sender authenticity, or investigating suspicious emails. While typical email displays show only basic information like sender, subject, and date, the complete header reveals the full path an email took from sender to recipient, including server information and security checks. Apple Mail provides a simple method to view these technical details. This guide explains how to view complete email headers using Apple Mail’s View menu, enabling access to diagnostic information for security verification and troubleshooting purposes.
