What server port numbers did you use?.
I have Incoming Server (POP3) set at 110 and Outgoing Server (SMTP) set at 26, no authentication on the test address and it still wont work for me.
*EDIT* The "Sending" part of the operation appears ok, its the recieving part that throws errors up:-
Although upon trying "Test Settings" in Outlook, it still fails to log into the server.
