Humm. This is something I have not run into before. Can you supply a URL that explains how to relay mail though a Telnet or RADIUS server?
Older versions of WinGate used to run a listener service on port 23 that would take a hostname and a port as input and connect to that. Real easy to abuse, and also to DoS itself - let it connect to localhost:23 a bunch of times and eventually Windows would run out of clean winsocks, thus solving the problem for a little while. -- Niels.
