This is not a problem for me, the end customer's IT boss asked me to see
if it is possible to do it, he dont like to publish theire private IPs
for 'Security reasons'.
If it is not possible, i have to give him convincing arguments.

Richid,
Why is it a problem that people see your internal IPs?
Thanks

Thank you Jeroen,
My need is to prvent peopel seeing my internal IPs, if i can make my
server write on the header 127.0.0.1 instead instead of the
192.168.0.2 is will be great.
I see on the header of your mail for example, all Received: tags
indicate 127.0.0.1, i want my server to do the same thing if possible.
Thank you

Hello List,
I have a mail relay and an internal mail server both under Postfix
and behind a firewall (DMZ and LAN), on both segment i'm using a
private IP address with NAT.
On all outgoing emails headers sent by our users, i can see my
servers ip addresses (private).
Is there any config that i can do to make postfix write hostname
instead of the ip address on the header or replace the private ip
address by the public ip address?
Thank you
Brest regards.
The format and content of Received: headers is described in detail
in the relevant RFCs.
Make sure you know why you want to mess with them before blundering
forward.

I guess I don't see how an internal private IP is a security risk.
