Hi MAbans & ryadex,
If insist on trying install email server, there is one used to be free SMTP Server for Win32 call Postcast http://www.postcast.com (latest 1.5, two weeks ago is shareware at present). It requires with local DNS server, I think! What type of connection you are using (i.e. are you connected through one ISP only).
If you want and can't find the free version(1.0) of Postcast, I'll forward the link so you can download from my backup FTP site.
Happy hacking :-)
