I began to experience a problemw with the Yahoo gateway a couple of days ago while using Spark 2.5.8 or 2.6.0 beta 2 and Openfire 3.6.4.
Another person I know is also having the same issue running a different system with the same versions.
Basically we can log in and see our roster but the roster does not auto update as people sign on/off and while we are able to receive messages from others we cannot send them messages, at least it appaears that we can but the receiving party never gets them. The debug log shows this:
2009.09.30 10:36:09 Received message packet: can u read this5b2A7e
2009.09.30 10:36:09 Failed to send message to yahoo user.
Could this be related to Yahoo’s change/updates in their protocols/network for their IM service? Anyone else experiencing this issue?
