Announcing Stalwart JMAP server
We are happy to announce Stalwart JMAP, an open-source JSON Meta Application Protocol server written in Rust that aims to be scalable, robust and secure.
Some of its key features are:
- JMAP Core, JMAP Mail and JMAP over WebSocket full compliance.
- IMAP4 rev2/1 support via Stalwart IMAP, an imap-to-jmap proxy.
- Scalable and fault tolerant: consensus over Raft, node autodiscovery over gossip and read-only replicas.
- RocksDB backend with full-text search support in 17 languages.
- OAuth 2.0 authorization code and device authorization flows.
- Domain Keys Identified Mail (DKIM) message signing.
- Written in Rust.
- No third-party software required to run or scale.
Currently Stalwart JMAP requires an SMTP server such as Postfix in order to receive e-mails. However, the next item on the roadmap is to release an SMTP server in Rust with the goal of making self-hosting an e-mail server much simpler without sacrificing any security.
