Thanks, everyone. Summary: Received: (single recipient only) Original-Recipient: (https://tools.ietf.org/html/rfc3798#section-2.3 DSN extensions) Delivered-To: (some MTAs) Envelope-To: (exim) X-Original-To: (postfix is configurable to use any header, examples use this) Original-Recipient is really close, but I don't think it's exactly the right thing, as it's intended for copying the envelope ORCPT (rfc 3461, DSNs) not the RCPT TO. That's the same thing before mail gets forwarded, but may not be after. /me is going to go with Envelope-To, as it's going to be the easiest to explain to users "this is from the envelope at SMTP delivery time, not the To: or Cc: or anywhere else".
