The driving force behind Cypht development is to provide combined views for multiple accounts, but it's also a standard E-mail client that lets you browse and manage IMAP folders and send outbound messages with SMTP
Cypht is an application built entirely of plugins, or as we call them, module sets (which is obviously way cooler sounding than plugins), that are executed by the framework. Modules provide a flexible way to add new features or customize the program without hacking the code
Cypht is Open Source (LGPL V2), and written in PHP and JavaScript. If you are looking for a lightweight webmail solution for an ISP, school, business, or just personal use, I hope that Cypht can help!
We want to hear from you! Drop by the Cypht Gitter channel. We take security seriously. Cypht is an entirely volunteer effort, so we can't afford a bounty program. We can however promise that any security issue reported to us before release will receive a quick response, a thorough review, a sincere thanks, and an honorable mention on this page.
Instead of an application with a plugin API, Cypht is an application comprised entirely of plugins, or as we call them, "module sets". There is only one required set, the "core" modules. The components of any module set can be added to, or even replaced, by site specific modules. All the functionality of Cypht is broken out into module sets, and each set is built from small pieces that are also easy to override.
