Stalwart and modern self-hosted mail

A high-level look at Stalwart Mail Server: why new mail stacks exist, what they optimize for, and how to think about mail without nostalgia.

Stalwart is a newer mail server implementation aiming at a modern feature set and APIs. Mail is famously easy to run poorly; projects like this exist because operators want clearer boundaries between SMTP, JMAP/IMAP, and admin surfaces.

Why mail still deserves respect

Deliverability, reputation, backups, and least-privilege admin paths are not optional hobbies. If you self-host mail, you are signing up for ongoing care, not a weekend trophy.

The project site stalw.art is the right place to compare components and roadmap reality before you cut MX records.

Stack pattern

Keep webmail and admin UIs behind the same reverse-proxy discipline as any other app: TLS at the edge, tight paths, and logs you can read.
