I have seen other topics that have no solution posted in the Leopard forums. Now that we have 10.6 and the problem still exists it's time for a new thread. The details. 1. Mail is set up exactly as it should be per Godaddy's site, and their phone tech support. 2. Mail is being received on a regular basis and works perfectly. 3. Some messages send, while others refuse to send with no pattern as to why. 3.1. When sending these stubborn messages - Mail quickly shows the status reach about halfway through the "sending message" progress bar in the lower left of the app and then immediately stops and says it can not send with the selected server. 4. Changing the message slightly sometimes allows the message to send, but not always. 5. Godaddy points the finger at Mac Mail as the culprit. So what can we do to start the troubleshooting process? How can we find out what Mac Mail is doing when it decides not to send these messages and just fail? This is getting really old, really fast. Thanks in advance.
