5291.0. "SLIP and Ethernet mail - how ?" by TAVIS::LANDSBERG (Internets success will also be its downfall) Mon Mar 03 1997 17:13

    Hi,
    
    I'm trying to do the following thing :-
    
    1. Run tcp/ip services to the local network on ethernet.
    
    2. Connect to an Internet provider via UCX/SLIP and a Terminal Server and
       transfer all mail, that is not destined for the host node, sent to the
       internet via the UCX/SLIP connection.
       
    We've written a program that automatically dials up and connects to the
    slip line. 
    
    Questions:
    
    1. How do I know that smtp mail is sent to the SLIP line and not stuck
       trying to find a path somewhere ?
    2. How does the system differentiate between local mail and external
       mail ?
    3. Do we need to configure something in MX ?
    4. The SMTP mail queues give the Ethernet host name, not the SLIP host
       name, do we need to define seperate SMTP queues for the SLIP
       interface ?
    
    Thanks for your help,

    Since noone answered, I'll answer my own questions.
    
    There is no need to do anything. Once I've setup the default gateway to
    the router on the other side of the slip line, then local mail stays on
    the local host and all other mail goes to the mail server on the other
    side of the slip line.
    
    So this is what I have :-
    
    1. A procedure dialing every few hours via a modem connected to a
    DECserver 200.
    
    2. The procedure then establishes a UCX SLIP line
    
    3. SMTP is activated and the queue is checked to see if it is busy.
    
    4. Once the queue is not active for several minutes, SMTP is halted,
    the SLIP line is deassigned and the procedure disconnects the modem.
