Email headers are metadata information added to an email message that contains details about the sending, routing, and receipt of the email. These headers are typically not visible to the average email user, but they provide crucial technical information for email clients and servers.
Some of the key information found in email headers includes:
Return-Path: The original email address to which any error messages or undeliverable messages are returned.
Received: A series of entries indicating which servers have received and relayed the email message, including timestamps.
From: The email address of the sender.
To: The email address of the recipient.
Subject: The subject line of the email.
Date: The date and time the email message was sent.
MIME-Version: The version of the MIME protocol used for formatting the email.
Content-Type: The content type of the email, such as text or HTML.
Email headers are invaluable for diagnosing email delivery issues, tracing the origin of an email, and identifying potential spam messages. We can use these email headers to investigate and resolve email-related problems.
