The Horde Team is pleased to announce the final release of the Internet Mail
Program (IMP) version H4 (5.0).

IMP, the Internet Mail Program, is one of the most popular and widely deployed
open source webmail applications in the world. It allows universal, web-based
access to IMAP and POP3 mail servers and provides Ajax, mobile and traditional
interfaces with a rich range of features normally found only in desktop email

To install IMP, you need to install Horde first. See
https://github.com/horde/horde/blob/master/horde/docs/INSTALL for  
details. Once
Horde is installed, you can install IMP with the following command:

   pear install horde/imp

Then log in to Horde with your adminstrator account to configure the
application and install the database schema from the configuration interface.

The major changes compared to the IMP version H4 (5.0-RC2) are:

     * Improved new mail notifications, now available in all applications.
