Open-source mail and collaboration server with JMAP, IMAP4, POP3, SMTP, CalDAV, CardDAV and WebDAV support. Written in Rust, designed to be secure, scalable, and easy to operate.
JSON Meta Application Protocol Specification (JMAP)
JMAP is the open protocol that replaces IMAP (and CardDAV and CalDAV). It’s faster, simpler, more powerful, and built for how email works today.

Home - maddy
Maddy Mail Server implements all functionality required to run a e-mail server. It can send messages via SMTP (works as MTA), accept messages via SMTP (works as MX) and store messages while providing access to them via IMAP. In addition to that it implements auxiliary protocols that are mandatory to keep email reasonably secure (DKIM, SPF, DMARC, DANE, MTA-STS).

Re-thinking electronic mail
There are many problems with the existing Internet email system, such as spam, scam, surveillance, insecurity, centralization, and complexity. The problems are starting to outweigh the benefits of the system. Fixing the problems by evolving the current system seems overwhelmingly difficult. This essay examines some solutions to the problems on the assumption that a completely new, parallel email system can be built.
