Deployment Setup
What an operator must configure for mail delivery.
1. Receiving domain
Set the receiving domain used to mint addresses, and point its MX records at Cloudflare Email Routing.
2. Inbound worker
Route all mail on the domain to a Cloudflare Email Worker that POSTs the parsed message to /api/public/email/inbound.
3. Shared secret
The worker must send the configured webhook secret. Requests without it are rejected.
4. Verify
Create an inbox and send it a test message. Once delivery works, the setup notice disappears from the inbox screen.
