The past few days i faced a problem with pidgin that it works with my msn e-mails and gmail e-mails but the problem was with yahoo.
Yahoo! Inc. did something to its messenger servers, something that practically blocked all the Linux IM clients, such as Pidgin, Kopete, Empathy or GyachI.Yahoo! changed the login method! However, at this moment none of the aforementioned Instant Messenger clients for Linux can connect with the Yahoo protocol.
i searched for the solution of this problem and finally found it 😀 , then let’s fix this problem !
the solution was in the latest version of pidgin 2.5.7
