yahoo.com.AU settings

Can you please tell me what settings are used to access the old YAHOO.COM.AU mail

It works fine in the addon, but I need to set up a mail client on another PC and it won't accept the username or password using the normal Yahoo settings. They are right, just not accepted by the Thunderbird program I'm trying to set up.

Or is there a file now on my PC from the addon that stores these I can look at?

Thx in advance - Trevor
