IMP facilitates online access to IMAP and POP3 mail servers through its web-based messaging software.
There are currently three branches of IMP available, each catering to specific needs and preferences. IMP 4.0 is the current production version of the stable branch, requiring PHP 4.3.0 and version 3.x of the Horde framework. It comes with several exciting new features, including crypting support, flexible charset handling, virtual folders for saved searches, a WYSIWYG editor for creating HTML messages, improved MIME message handling, and much more.
IMP 3.2.7 is the current production version of the previous stable branch, requiring PHP 4.1.0 and version 2.0 of the Horde framework. It offers advanced features such as searching multiple mailboxes, identities, and a hierarchical mailbox navigator, as well as a cleaner, redesigned user interface. In addition, IMP 3.2.7 passes UW's "MIME Torture Test," ensuring optimal performance and reliability for users.
IMP 2.2 is the previous stable branch, now obsolete, that used PHPLIB for session management and worked with both PHP3 and PHP4. However, version 2.2 is no longer actively developed, and sites still running this version are urged to upgrade to 3.x as soon as possible due to known security issues.
This latest release of IMP brings several new features and improvements, including a server configuration option to limit login attempts, a link to view attached S/MIME key details, fixed folder name escaping, and updated translations for Catalan, German, and Slovenian. Furthermore, several small bugfixes and enhancements have been added, ensuring that IMP remains one of the most powerful and reliable webmail access tools available today.
