Gateway plugin test failed for MSN/Yahoo

Openfire Plugins Community Plugins

I just installed gateway.jar plugin. In Admin console, I tried to test them, but failed.

The default server names/ports are:

MSN: messenger.hotmail.com

port: 1863

YAHOO: scs.msg.yahoo.com

port: 5050

Are they correct? If not, how to find their server names and port numbers?

Thanks

Dave
