Hi again,
Well, while I've done so many things lately I don't remember, but
I'm pretty sure I never did any TCP setting in classic (9.2.2 for your
reference) & checking that machine now shows no TCP/IP control panel, yet
SIMS is still able to deliver mail to another 'real world' server remotely,
so my guess is it is able to see the OSX stack. You may be right about the
UDP/TCP part listed above.

Bye for now, Terry Allen
