This question already has an answer here:

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?

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.

this seems to conflict with the answer at… which indicates the answer is implementation-specific... ? – Robert Jul 23 '13 at 20:19
No. Read that again. The CLIENT (MUA) ma decide to include the old headers in the new email. But that is not part of the SMTP protocol. A SMTP Server wont delete them. If that happens, it is totally a client functionality. – TomTom Jul 24 '13 at 3:09
