K-9 Mail is an open-source email project that can be a useful alternative to more mainstream options such as Yahoo! Mail or Gmail. Due to this nature, it is free to download and updates generally take place on a regular basis. High levels of encryption as well as the ability to support multiple accounts are other benefits associated with this package.

Main Features and Accessories

K-9 Mail is intended to be a flexible and highly intuitive email platform. Although a standard inbox is offered, the user also has the option to create other color-coded folders intended to filter mail into different sections. This same type of color coding is listed within the main display, so it is much easier to identify specific senders and recipients. Its top-down scrolling function is extremely useful for mobile phone users while the entire screen can be resized to zoom in on a certain correspondence.

Technical Information and Other Benefits

K-9 Mail supports IMAP push email functions, multiple folder synchronization, the ability to flag incoming messages and the possibility to add personalized signatures as part of a standard template. This system can also work with POP3 and Exchange 2003/2007 architecture. Synchronous applications can work with K-9 to add extra levels of inter-user encryption.
