Stalwart
An open-source all-in-one mail server developed in Rust that integrates SMTP, IMAP, JMAP and spam filtering and other mail protocol stack capabilities within a single process.
Timeline (last 90 days)
For teams considering replacing their existing mail system, Stalwart v1.0 should be seen as a starting point worth watching rather than a signal to migrate immediately.
Stalwart chose Rust as its implementation language, leveraging its memory safety guarantees and zero-cost abstractions to achieve more stable latency under high concurrency.
Stalwart v1.0 sparked discussion on Hacker News; the discussion was modest in scale, but the focus was on how the performance figures were measured, how it performs under real workloads compared with mature solutions such as Postfix, migration costs, and whether it supports common authentication and filtering extensions.
The mail server market has lacked fresh blood for years, and Stalwart's emergence shows that modern systems programming languages are permeating the traditional infrastructure domain, and that the value of an integrated architecture in simplifying deployment is being taken seriously again.
Stalwart v1.0 has been officially released, positioned as a mail server.
Stalwart v1.0 uses "the world's fastest mail server" as its promotional pitch.
Stalwart carries all of the mail service's core functionality in a single binary to reduce inter-process communication and configuration synchronization overhead.
Stalwart是用Rust编写的现代邮件服务器，支持JMAP、IMAP4、SMTP等协议
Stalwart 是一个用 Rust 编写的现代邮件服务器，支持 JMAP、IMAP4、SMTP 等协议
AurionMail 是一套集成了 CryptPad 和 Stalwart 的端到端加密办公套件，提供邮件、文档协作等功能，采用单密码用户体验
