Catch every email your app sends
Nothing gets delivered. Every message lands in a local web UI instead. An SMTP mail catcher for dev and test environments, in one binary.
$ docker run -p 1025:1025 -p 8025:8025 smyile/rustmail:latest
SMTP listening on 0.0.0.0:1025
Web UI → http://localhost:8025
What it does
Persistence, search, a REST API, and a single binary you can drop into CI.
Emails survive restarts
SQLite-backed by default. Ephemeral mode for throwaway CI runs.
Full-text search
SQLite FTS5 across subject, body, sender, and recipients.
Real-time inbox
WebSocket push. Dark mode. Keyboard shortcuts. Instant delivery.
Built for CI
REST assertions, CLI assert mode, and a GitHub Action for your pipeline.
Single binary
Frontend embedded at compile time. One binary, zero runtime dependencies.
REST API + OpenAPI
Full API spec. Export emails, release to SMTP, webhook notifications.
The web UI
Keyboard shortcuts, live updates over WebSocket, and a theme that follows your system.
Or stay in the terminal
The same inbox, the same search, without leaving your shell.
