SquirrelMail 307
Platforms
SquirrelMail is available for any platform supporting PHP. Most commonly used platforms include Linux, FreeBSD,
Mac OS X and the server variants of Microsoft Windows.
Future development
New releases of the stable SquirrelMail product are made as needed to address any bugs or security issues which
may be discovered. Development of new features and enhancements is concentrated on the development product,
which, in time, will itself become the stable product. The SquirrelMail 1.5 Roadmap [16] outlines some of the
features slated for the next developmental release, including:
• A templating system
• A RPC interface for use by other applications as well as AJAX-enabled SquirrelMail template sets (skins)
• A new initialization system
• Faster login times due to improved message header caching
• Security enhancements, such as HTTPOnly cookies
• Improved usability/accessibility
Plugins
The SquirrelMail client itself is a complete webmail system, but extra features are available in the form of plugins. A
plugin allows non-standard features to be added to SquirrelMail, often without the need to modify the source code.
There are over 200 third-party plugins available for download from the SquirrelMail website, [5] and SquirrelMail
ships with several "standard" or "core" plugins, allowing an administrator to add:
• Spell checking (squirrelspell)
• Mail filters (filters)
• Web-based administration of SquirrelMail (administrator)
• A calendar (calendar)
• An interface to submit bug reports semi-automatically (bug_report)
Examples of functionalities added by various third-party plugins include:
• Address book/contact grouping and other address book expansions
• Monitoring and security tools to track usage, fight attackers and improve security
• Password change
• Quota reporting
• Rich text (HTML) email composition and display
• User-configurable front-ends for autoreponders, spam filtering systems such as SpamAssassin and server-side
mail filters
• Weather reporting
• User account control panel
