E-mail properties show Network Source!

Without some form of masqureding, I think that it is quite hard, since that is part of the standard MIME header. Unless it can be edited, I can only suggest. Also if you can, post a pseudo email to show it.

Example:
Return-Path:
Delivered-To: log@mx.imec.ro
Received: (qmail 2258 invoked by uid 504); 17 Jun 2002 08:31:00 -0000
Received: from unknown (HELO COMPUTER2) (200.200.200.58)
by mail.imec.ro with SMTP; 17 Jun 2002 08:31:00 -0000
Received: by COMPUTER2 with Microsoft Mail

Message-ID: <01C215F2.730F80E0@COMPUTER2>
From: User1
To: "'User2@hotmail.com'"
Subject:

MIME-Version: 1.0
Content-Type: multipart/mixed; boundary="---- =_NextPart_000_01B215F2.730F80E0"

Well, agree that it is difficult.

However it is easy to make this information meaningless to outsiders. Use NAT (Network Address Translation) in your firewall/DMZ complex, which is a main security bonus anyhow. Then the address in the mail header, and the DNS name, are basically meaningless for any mail recipient outside the company - they cannot ping the address, not find the computer name anywhere on the Internet, etc. etc.

Success,
