I build the sip-communicator source code and run it on the eclipse IDE in
Ubuntu Linux. when I'm going to register a new account with a yahoo ID it
always displays an error message "An error occured while logging in with the
following account: User name: charithcs, Server name: yahoo.com."
I'm sure the provided user name and the password are correct. But for MSN
account it works perfectly. Can anybody tell me what's the reason for this?
