Let’s say an email is sent from party A to B. Let’s refer to the set of headers that B views as Headers 1. Party B then replies to or forwards the email to party C. Let’s refer to the set of headers that C views as Headers 2. Does any information from Headers 1 persist separate from or as a part of Headers 2?
Answer
No. SMTP Has no concept of forwarding. You basically send a new email. And that is technically correct – after all, you send the new text to your email server.
