/* More software from HardCore.WantaBe.Com...
* Haha, well its only been a day, and I'm coming out with a new version.
* If you haven't noticed, it uses proxies to send the mail, thus making
* it appear to be from that host in the header of the mail.
* After connecting to the proxy (remember, a wingate is a proxy) you are 
* connected to the SMTP server.
* The SMTP server MUST have relay turned on. This is still beta, 
* but now it works with more proxies. Maybe i'll put out with v0.3 tomorrow :P
* (check out line 73 for some comic relief)

* --------------
* Here is an example of what yahoo shows when you recieve mail using 
* incognitomail2, I have edited out what sendmail server I used, and the 
* address of the insecure proxy server used.
*
*   X-Apparently-To: kilrid@yahoo.com via web2003.mail.yahoo.com
*   Received: from relay.sendmail.server (HELO relay.sendmail.server)
*   (2.2.2.2) by web2305.mail.yahoo.com with SMTP; 23 Apr 2000
*   20:51:30 -0000
*   Received: from kilrid (insecure.proxy.com [2.2.2.1]) by
*   relay.sendmail.server (8.9.3/8.9.3) with SMTP id QAA21131 for
*   kilrid@yahoo.com; Sun, 23 Apr 2000 16:51:35 -0500
*   Date: Sun, 23 Apr 2000 16:51:35 -0500
*   From: kilrid@kilrid.org
*   Subject: kilrid rules
*   yay, incognito mail v0.2 works.
*   ---------
* yada yada, this is for educational purposes only, I don't take any 
* responsibility for others actions using this, etc etc.
