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 — with a live dashboard, and nothing phoning home.
A dozen providers, one relay
Swap between providers per relay without touching your apps. CC/BCC, attachments, and custom headers everywhere.
📥 Local Inbox — for developers
Test what your app actually sends without delivering anything. Set the relay to Local and inspect every message — subject, headers, To/Cc/Bcc, rendered HTML & text, and attachments — right in the dashboard. A built-in mail trap, no third-party service.
🔒 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 — 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.
