I sent a mail from my machine relayed through a ~~public~~ mail server to my gmail account using smtp on telnet.

now when i select show original on for that mail in my gmail account.

I see several headers just before the body of my mail.

X-TM-AS-Product-Ver:
X-TM-AS-Result:
X-imss-scan-details:
X-TM-AS-User-Approved-Sender:
X-TM-AS-User-Blocked-Sender:

Are these headers being added by gmail or my mail server. How do I find out.

Is this because of the process described in Section 3.8.1 of this rfc.
