About Stalwart Mail Server
Stalwart Mail Server is a modern, all-in-one mail server that handles both sending and receiving email. It supports JMAP, IMAP, and SMTP protocols, and includes a built-in spam filter, sieve scripting, and full-text search. The server is written in Rust, which gives it strong memory safety and high throughput.
It runs on Linux and can be deployed via Docker or directly on bare metal. Stalwart integrates with LDAP or SQL databases for user authentication, and stores messages using FoundationDB or RocksDB. The project is developed by Stalwart Labs and is fully open source under the AGPL-3.0 license.
This is a good fit for sysadmins who want a single mail server stack without piecing together Postfix, Dovecot, and Rspamd. It is actively maintained and has a growing community. The documentation is thorough and includes quickstart guides for common deployments.
