This project is a fork of Rainloop and aims to apply hardening, modernization and a more lightweight experience.
For a detailed overview on installing SnappyMail, please see the installation instructions.
To learn how to contribute code to SnappyMail, please see the contributing instructions.
This fork implements the following changes in comparison to upstream:
- Privacy/GDPR friendly (removed Sentry, Gravatar, Facebook, Google, Twitter, DropBox, OwnCloud and X-Mailer links/inclusion)
- More secure admin hashing algorithm (uses password_hash/password_verify)
-
Added features/functionality:
- Auth failed attempts written to syslog (for fail2ban and others)
- Option to remove background/font colors from messages for real "dark mode"
- Modified Squire HTML editor as replacement for CKEditor
- Better memory garbage collection management
- Advanced Sieve filter scripts editor
- No user-agent detection (use device width)
- Split Admin specific JavaScript code from User code
-
More modern PHP approach:
- Requires PHP 7.3+ with the mbstring extension
- Replaced pclZip with PharData and ZipArchive
- Prefer the yaml extension, fallback to the old Spyc
-
Removed features/functionality:
- Background video support
- BackwardCapability (class \RainLoop\Account)
- ChangePassword (re-implemented as plugin)
- OAuth support
- POP3 support (this fork supports only IMAP)
- Ongoing removal of old JavaScript code
- Dropped gulp-uglify in favor of gulp-terser
- Replaced webpack with rollup
This fork uses downsized/simplified versions of scripts and has no support for Internet Explorer, resulting in increased performance and a smaller pageload - which benefits mobile devices. Things might work in Edge 15-18, Firefox 47-62 and Chrome 54-68 due to one polyfill for array.flat().
- Removed pikaday
- Removed underscore
- Removed polyfills
- Removed Modernizr
- Removed nanoscroll
- Removed lightgallery
- Removed jQuery
- Removed matchmedia-polyfill
- Removed momentjs (use Intl)
- Removed opentip (use CSS)

For a user its around 70% smaller and faster than traditional RainLoop.

The Squire implementation is not 100% compatible yet, but it shows the massive overhead of CKEditor.
Still TODO:
- support for tables (really needed?!?)
- support BIDI (really needed?!?)
