Are ur relay server services working?
What do u see when u hit this page
http://relayserverip/ias_relay_server/server/rs_server.dll
What i can see is that even if the port is opened in telnet the relay server is switched off because of this the Outbound enabler is not able to connect to Relay Server.
Check in services.msc if you have configured Relay Server to start as a service.
Thanks,
