I think that's the point - sending mail directly to an IP address is a  
non-scalable solution. Once the internet expanded past a few dozen  
machines this became apparent.

That said, you can do it - the SMTP standards call for enclosing the  
IP address in brackets, so address your mail to:

	user@[192.168.1.2]

and it'll go to that server.

Still not sure why you don't want a central solution, though...?
