headers

We have a domain (domain.local) that has IP Addresses in the 10.10.10.* range. In the outbound SMTP server traffic, I see the internal machine name (exchange.domain.local), and the internal ip address (10.10.10.55).

The question is, how do you remove this header from exchange, or change it to have the external machine name/ip addresses.

I am not talking about the HELO / EHLO handshake as part of the protocol.

Please help.
