Setup guide

Follow these steps once real backend connection values become available.

Select the correct Mailflow project in the dashboard header.
Choose its Test or Live environment.
Create a scoped SMTP credential and store its one-time secret securely.
Copy the backend-provided host, port, TLS mode and username.
Configure your application with encrypted SMTP and the scoped credential.
Test a real connection only after the SMTP backend is available.

Illustrative application configuration

These examples are configuration sketches, not verified working connections.

// Illustrative configuration only — no connection is opened.
const smtp = {
  host: "smtp.mailflow.invalid",
  port: Number(process.env.SMTP_PORT), // backend-assigned port
  tlsMode: "<BACKEND_ASSIGNED_MODE>",
  username: process.env.SMTP_USERNAME,
  password: process.env.SMTP_PASSWORD,
};
