Dvisd email header

An email header is the part of an email that contains information about the email, such as the sender, recipient, subject, date, and other metadata. Here is an example of an email header:

From: John Doe <[email protected]>
To: Jane Smith <[email protected]>
Subject: Meeting Invitation
Date: Wed, 12 Apr 2023 14:30:00 +0000
Message-ID: <[email protected]>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 7bit
X-Mailer: Mozilla Thunderbird 78.10.0
X-Originating-IP: [192.168.1.100]

Here's a breakdown of each field:

• From: The sender's email address and name.
• To: The recipient's email address and name.
• Subject: The subject line of the email.
• Date: The date and time the email was sent.
• Message-ID: A unique identifier for the email, used to prevent duplicate delivery.
• MIME-Version: The version of the Multipurpose Internet Mail Extensions (MIME) standard used to format the email.
• Content-Type: The type of content in the email, such as text or HTML.
• Content-Transfer-Encoding: The encoding used to transfer the email content.
• X-Mailer: The email client or program used to send the email.
• X-Originating-IP: The IP address of the computer that sent the email.

Note that not all email headers contain all of these fields, and some may have additional fields depending on the email client or server being used.
