Well, the way it works is, we connect to messenger.hotmail.com on port 1863, and they redirect us elsewhere. The MSN protocol has many many TCP connections in it. You could assume they would all be in Microsoft's IP block. So if you could find out what that was, and allow connections to it on port 1863, all should be good. Just allow the machine with the transport to make outgoing connections to any host on port 1863. --- James
