Hi Greg.

You are close to what I am trying to do, and where I am.
I can't get the Home mailserver to connect and relay through the DSL 
Mailserver, an authentication issue that I do not know how to solve.
ISP has their DSL clients behind several firewalls, and NATed a couple 
of times to boot, so I can't access home system from on the road.  And 
by NATed, I mean my system is NATed, and the gateway I am using is NATed 
to an Internal address.  My home system is about two hops from an 
external IP address.  So laptop needs a slightly different solution from 
the home network.  This is why I am looking to figure out a new arrangement.

I've got SuSE Config & Yast to handle configs, but I am missing 
something somewhere in the instructions, and I don't know enough to 
figure out where.

Regards,
Steve
