I don't see the problem.

What you really want to do is the following (for example):

----- BEGIN EXAMPLE
HELO joes_pc.umd.edu
MAIL FROM:<dzoey@maildrop.umd.edu>
RCPT TO:<jordan@ucbarpa.Berkeley.EDU>
DATA
Received: by joes_pc.umd.edu id AA25297; Mon, 16 Feb 87 18:15:50 EST

Subject: Some mail for you ...

.
----- END EXAMPLE

You do in fact need to tell the truth in the HELO statement, but
are free to hack your outgoing mailer to give a different FROM
address ...
