One of the solution may be using internal dns for each client. If you have
windows 2000 domain structure, you can do this using DDNS (Dynamic DNS). In
this case dns records will be exposed instead of IP address in the mail
header.

Subject: How to hide local IP from outlook email

Hi All,
We are using outlook as mail client and we have IIS 5.0 SMTPSVC as SMTP
gateway.

When we sent email out, we noticed in the email header, the information
like IP address of the machine that sending the email is in the email
header.

We don't want this because it exposed our internal network.

So, anyone know how to solve this or any workaround?

Thanks
