Would still be interesting to see if this is possible, but I found a work around in Sendmail to just add:

H?P?X-Envelope-To: $u

Note that the $u macro will be defined if and only if there is 

one and only one recipient for the current message. This will not be the case for mailing list mail being sent by the server, unless you have turned on list customization. In that case, mailman will send out one copy of the message for each and every recipient, and will put their e-mail address in the footer.

Also, in the case of a single recipient per message, most MTAs 

are already configured to put this kind of information into the headers, usually the "Received:" headers.
