So configure your MTA to send the NAT proxy address in the HELO; this might make other MTA's on your LAN unhappy, but the world outside sees a kosher HELO with the exact hostname of the host it's coming from. I don't know how to do this with Sendmail or Postfix; with qmail, all it took was a one-line /var/qmail/control/helohost containing the desired hostname to send.
