MailSync is a beautiful proof of work for the NDN project with the potential to make NDN's value understood through the popularization of this app. This project focuses on doing so by refactoring the app to remove unwanted behaviors occurring in the app. The project will add major testing code and benchmarking code to ensure that the application continues to be stable. Furthermore, additional security measures and validation will be added to the application. To popularize the app, the UI and UX of the app will be brought up to standards and NDN theme will be incorporated into the application.
