I'm using a pop3 server on mail.mydomain2.com.
I'have received a message from mail.mydomain.com and
in the header message there are the following text lines:

Received: from mail.mydomain.com ([194.194.194.194])
 by www (8.10.2/8.10.2) with SMTP id e9G9FZq12616
 for <[EMAIL PROTECTED]>; Mon, 16 Oct 2000 11:15:35 +0200
Received: (qmail 2553 invoked from network); 16 Oct 2000 09:09:58 -0000

                        ^^^^^^^^^^^^^^^^^^^^^^^           
 by 192.168.0.2 with SMTP; 16 Oct 2000 09:09:58 -0000
^^^^^^^^^^^^^^
...

In the header appears the host name and the ip address
of the client sender and the internal ip address of the
qmail server (either protected by firewall).
How to scrub the private ip addresses from the header?
Thanks in advance for any help.
