Self-hosted email relay

The email relay you
host yourself.

Point your apps and devices at Dispatch over SMTP or HTTP. It queues every message durably and forwards to any provider โ€” with a live dashboard, and nothing phoning home.

Dispatch dashboard

A dozen providers, one relay

Swap between providers per relay without touching your apps. CC/BCC, attachments, and custom headers everywhere.

๐Ÿ“ฅ Local Inbox โ€” for developers

Test what your app actually sends without delivering anything. Set the relay to Local and inspect every message โ€” subject, headers, To/Cc/Bcc, rendered HTML & text, and attachments โ€” right in the dashboard. A built-in mail trap, no third-party service.

๐Ÿ”’ No call home

No telemetry, no analytics, no update pings. Even license checks are fully offline. It only connects to the providers you configure.

Two ways in

SMTP (25 / 587 / 2525, STARTTLS) or a Mailgun-compatible HTTP API with per-key tokens.

Durable spool

Instant 250 OK to a local queue โ€” mail keeps flowing even if the database is down. Auto-retry with back-off.

Deploy anywhere

Windows & Linux installers (bundled SQL), a multi-arch Docker image, or a ready-to-import virtual appliance.

Keep your mail on your infrastructure.

Self-hosted, offline-licensed, and yours to run.
