We are pleased to announce that we’re ready for users to test our new webmail application. It features a modern interface that utilizes ajax and html5 and supports features like drag-and-drop and has a robust plugin system that allows us to extend its functionality. All of our existing webmail applications will be replaced by the new one on April 22nd. We encourage users to start using it now – it really is better in just about every way!
For now it is available at https://webmail-beta.sonic.net
Please let us know if you have any questions or feedback in the forums.
