Stalwart Labs

Stalwart Labs Ltd is the creator of Stalwart Mail Server, a modern and user-friendly mail server software designed to revolutionize self-hosting. In the past, managing your own mail server has been a daunting task, but not anymore. Stalwart offers a scalable, secure, and robust solution that makes it easy to modernize your mail server.

Stalwart Mail Server is built around JMAP, a modern protocol for accessing emails and other data. It is incredibly fast and ensures memory safety with its Rust-powered engine. With no runtimes or garbage collectors, it delivers impressive performance.

But that's not all! Stalwart also offers JMAP, IMAP, and SMTP servers, each with their own unique features and benefits. Stalwart JMAP is a robust, secure, and scalable JSON Meta Application Protocol server, while Stalwart IMAP supports both IMAP4rev2 and IMAP4rev1, offering multiple IMAP4 extensions. Stalwart SMTP is a modern server that prioritizes security, speed, and extensive configurability.

With Stalwart, you can be confident in the safety of your data. The mail server stores metadata and settings in SQLite or FoundationDB, a high-performance distributed database. Plus, email messages are stored separately from metadata, ensuring optimal security.

For support, you can turn to the vibrant community on Github or Discord, or become a sponsor for direct assistance from Stalwart Labs Ltd. So why wait? Upgrade your mail server experience with Stalwart today.
