How can I display FULL HEADERS of incoming messages?
Besides the basic information like the addresses of the sender (From:) and the recipient (To:), the subject (Subject:) and the date (Date:), the Full Mail Headers is the complete set of Email headers added by the sender's email software and related Mail Servers during the email delivery process. It contains very useful information of the email message delivery and routing, including IP addresses involved, time sent and the sources of the email. For more detailed explanation of Email headers please refer to this document.
The following are the Full Message Headers of a sample message:
