Also keep in mind that tampering with Received: headers is completely against RFC2821, not to mention a pain when someone is trying to troubleshoot something. I don't see a security issue here - if your internal addressing is RFC1918 private space (10.*, 172.16-31.*, 192.168.*) then you have nothing to worry about, and if not then you should be firewalling the world out anyway.
