The states and signals were painful to follow due to bad naming and excessive overloading. Here: - Renamed some API to avoid overloading, help readability and allow new connect() syntax without resolving the overloads. - updateStatus() signals and slots renamed a bit to make it clearer what is a signal and what is a slot. And avoiding overloading QMailMessageService::updateStatus() to simplify signal connection. - Cleaned up QMailTranport API. It's not doing urls but hostnames and the signals were especially hard to follow - Use the new connect() syntax in messageserver side - Avoiding some protected: / virtual methods when there's nothing even able to inherit the class. - At least print SSL errors instead of signal that's not connected anywhere. - Some minor simplifications and code style adjustments. The SSL error handling is still funny but at least a bit easier to track.
