Please, explain, what does it mean? "Yours will add a Received: header, and leave mine in tact."
As I understand this process in Imail example: to connect any server you need to create first D*.SMD and Q*.SMD files. Lets say for example that I want to forge the header and send my mail from my server1 throught your server2 to other server3. First of all I modify the D file and insert in the first line something familiar: Received: from list.microsoft.com [666.666.666.666] by zombie.com with ESMTP (SMTPD32-8.05) id AC37F47500BC; Fri, 06 Aug 2004 18:40:23 +0600 Then I try to connect to server2 to deliver this letter. You server accept the connection. And now i _can't_ modify anything in this D file, Your server just download the copy of this D file and then insert this legal line: Received: from _NORMALHELO_ [_NORMAL.IP_] by server2.com with ESMTP <-this is the open relay ip (SMTPD32-8.05) id AC37F47500BC; Fri, 06 Aug 2004 18:40:23 +0600 Received: from list.microsoft.com [666.666.666.666] by server1.zombie.com with ESMTP (SMTPD32-8.05) id AC37F47500BC; Fri, 06 Aug 2004 18:40:23 +0600 ...and forward mail to server3, then server3 insert next legal string Your mean that you can modify the first line from server1?

It is possible with Outlook Express. I mean >to forge header Received: content. This is pretty simple to explain. When your mailserver receives an E-mail, it can't trust any of the headers that the remote mailserver send it. Therefore, you can only trust headers that are added by your mailserver -- and in those headers, you can only trust information that you know is reliable.
