How to complete header of mail

The header of an email is the part that appears at the top of the email, above the subject line. It typically includes information such as the sender's email address, the recipient's email address, the date and time the email was sent, and other metadata. Here's a breakdown of the different parts of an email header:

  1. From: The email address of the person who sent the email.
  2. To: The email address of the person or people who received the email.
  3. Subject: A brief summary of the email's content.
  4. Date: The date and time the email was sent.
  5. Message-ID: A unique identifier assigned to the email by the email server.
  6. References: A list of message IDs that refer to previous emails in a conversation.
  7. In-Reply-To: The message ID of the email that this email is a response to.
  8. X-Mailer: The email client or program used to send the email.
  9. X-Priority: The priority level of the email, such as "High" or "Low".
  10. Content-Type: The format of the email's content, such as "text/plain" or "text/html".

Here's an example of what an email header might look like:
