Novell TCP-IP, it costs extra, but gives you full support for the TCP-IP 
protocol

You want two ISDN routers, Livingston make some good ones with Terminal 
Adapters on both, which can plug straigth into a ISDN connection.

Err... yes... see below

It is possible to set up one of the routers mentioned above to dial on demand, 
connect to the host, and send the mail and then hang up.  You could even get 
away with having MS-Mail just send the request and have the router do the work 
(that is if ms-mail can talk TCP-IP, I am not sure)  Otherwise, having a basic 
FreeBSD box (386 even) could handle what you want with ease.

The problem with NT is that it is not made to be a router.  It has router 
support but the memory it chews is heaps.  You are better off getting one of 
the routers made by Livingston/CISCO/Bay Networks etc and using that as a 
router.  Most of the good ones come with a built in firewall and connectors to 
Eathernet, Async ports and ISDN lines.

Good Luck
