What SnappyMail is

SnappyMail is a free, open-source web email client for self-hosted deployment. Install it on a web server, configure mail settings through its administration page and use it in a browser; no database is required. Listed protocols are IMAP, SMTP and Sieve. The interface supports responsive design, dark mode, message sorting and spam-score display. OpenPGP-related support includes GnuPG, Mailvelope, OpenPGP.js v5, PGP/Inline, PGP/MIME, ECC keys and whole-message encryption. Security controls include syslog login errors, Sec-Fetch checks and administrator TOTP two-factor authentication. SnappyMail is a RainLoop fork adapted for newer browsers, but most RainLoop plugins need replacements or code changes. It requires PHP 7.4 or newer and is licensed AGPL-3.0. The project recommends separate web and mail servers and says only the latest version receives security updates. POP3 is listed as unavailable.
