The drastically upgraded & secured fork of RainLoop Webmail Community edition.
SnappyMail began its life as a fork of Rainloop because of the lack of communication from the dev team behind the project. Namely, after a critical security breach was found in late 2021, users waited for an official patch that secretly released in june 2022 without any talk on the subject.
