Home
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.
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 68% 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?!?)
