David,

You seem to be pretty insistent that the problem is the "localhost" in
your "Received:" headers.

I'm not as sure as you are, and I'd like to know why you feel that way. 
At some point every linux/unix box email originates as localhost; are
you saying that no one can ever use a linux box to originate email? 
Somehow I don't think so.

Any system that would refuse mail where the first (bottom-most) received
header indicates "localhost" as the sender is most likely seriously
broken.

Furthermore, Received headers should only be modified by MTAs that
transport the email, and they should only add their own.  If you start
modifying received headers (unless you're quite careful) lots of
sophisticated spamtraps may start blocking your emails.
