Glad you got it working again! In the history of the file on GitHub, those lines for Mail have never existed, so it must have come from your side. Manual installations are easy to mess up and hard to keep up to date. There is a beta Jython addon, but that will be obsolete after I push out some addons to the Eclipse IoT Marketplace. They are actually out already, but I need to push an update to the libraries (install the libraries first!).
