The '''Internet Messaging Program''' or '''IMP''' is a [[webmail]] client. It can be used to access e-mail stored on an [[IMAP]] server. IMP is written in [[PHP]] and a component of the [[collaborative software]] suite [[Horde (software)|Horde]].

It is included with [[cPanel]] and [[Plesk]] installations as a webmail client. It often integrates [[email]], [[calendar]], [[address book]], notes, tasks, [[mail filter|filter]]s and a [[News client|newsreader]] with cPanel.

Internet Messaging Program is [[free and open-source software]] subject to the terms of the [[GNU General Public License|GPL-2.0-only]] license.

==History==
Chuck Hagenbuch published a first version of IMP on [[Freshmeat]] in 1998.<ref>{{cite web|url=http://www.horde.org/papers/oscon2001-case_study/|title=Horde case study|publisher=www.horde.org|access-date=2012-01-21}}</ref> A constant stream of feature requests not all fitting for a webmail application led to the development of a more generic [[web application]] backbone: the [[Horde (software)|Horde framework]]. The release of IMP 3.0 and Horde 2.0 was the first one with two truly separate components.<ref>{{cite web|url=http://marc.info/?l=horde-dev&m=101003795801512&w=4|title=Horde-2.0 release|publisher=marc.info|access-date=2012-01-21}}</ref> Since then any deployment of IMP can only run on top of a Horde installation.

SAPO uses IMP<ref>{{cite web|url=https://codebits.eu/Ghunti|title=Horde powering portugalmail.pt|publisher=codebits.eu|access-date=2012-01-21|url-status=dead|archive-url=https://web.archive.org/web/20120128114924/https://codebits.eu/Ghunti|archive-date=2012-01-28}}</ref> to provide several million users with a webmail platform.<ref>{{cite web|url=http://janschneider.de/consulting.support/references|title=Horde developer supports SAPO|publisher=janschneider.de|access-date=2012-01-21}}</ref> The company also sponsored the initial development of the dynamic [[AJAX]] variant of IMP<ref>{{cite web|url=http://janschneider.de/news/25/252|title=SAPO sponsors dynamic webmail|publisher=janschneider.de|access-date=2012-01-31}}</ref> which was released as a separate package - named DIMP - with the release of Horde 3.2.<ref>{{cite web|url=http://janschneider.de/news/5/322|title=Horde 3.2 and DIMP 1.0 release|publisher=janschneider.de|access-date=2012-01-31}}</ref><ref>{{cite web|url=http://ajax.phpmagazine.net/2006/02/imp_webmail_with_ajax_dimp.html|title=Development of DIMP 1.0|publisher=phpmagazine.net|access-date=2012-02-01|archive-url=https://web.archive.org/web/20120203231157/http://ajax.phpmagazine.net/2006/02/imp_webmail_with_ajax_dimp.html|archive-date=2012-02-03|url-status=dead}}</ref>

Support for mobile clients was provided within 2006 for the first time. At that time a WAP based mobile view was provided by a separate package called MIMP.<ref>{{cite web|url=http://lists.horde.org/archives/announce/2006/000283.html|title=MIMP 1.0 release|publisher=horde.org|access-date=2012-01-31}}</ref>

With the release of Horde 4.0 the three existing views were collapsed into the original IMP package again. In addition another mobile view for smartphones was added based on the [[jQuery Mobile]] [[JavaScript]] framework.<ref>{{cite web|url=http://log.pardus.de/2010/11/screenshots-of-new-horde4-mobile-portal.html|title=Development of the Horde smartphone views|publisher=log.pardus.de|access-date=2012-01-31}}</ref><ref>{{cite web|url=http://www.techworld.com.au/article/382641/open_source_horde_groupware_reaches_version_4/|title=News coverage of the Horde smartphone views|publisher=techworld.com.au|access-date=2012-02-01|archive-date=2012-02-02|archive-url=https://web.archive.org/web/20120202224218/http://www.techworld.com.au/article/382641/open_source_horde_groupware_reaches_version_4|url-status=dead}}</ref>
