I also Placed the 2 wspcfg.ini files into the appropriate directories on my Exchange Server, and set up my proxy client on one client workstation (win98).
Now when i try and send an external e-mail it get's bounced back with the following message:
__________

Also, one other odd thing is that when i run winipcfg on the client PC it shows my node type as peer-peer.
Does anyone have an idea of where i went wrong?
Many Thanks, Kal
Inbound mail might still be going to your old ISP, you will have to run nslookup and check the MX recordpoints to an A record which resolves to the external IP address of your proxy server.
