First run

At the end you know that the wizard shows your own servers and that the support page works.

1. Check that it is alive: curl http://localhost:8080/healthz answers ok.
2. Open http://localhost:8080, type an address on your domain and go through a guide. The IMAP and SMTP hosts, ports and security labels must be yours. If they are not, fix MAIL_HOST and the related variables in Configuration.
3. Open the settings panel in the page header (“Paramètres” in the French interface): it lists the same values, grouped, for advanced users.
4. Check /api/config: it is exactly what the browser receives, and contains nothing secret.
5. Set SUPPORT_PASSWORD in .env, run docker compose up -d, then open /support and sign in with SUPPORT_USER (support by default). Until a password is set, /support answers 404.

Before you announce it to customers, set PUBLIC_URL to the address they will use: links and QR codes are built from it.

Back up

Nothing is stored by the application. Keep your .env (it holds SUPPORT_PASSWORD; it is never committed) and any logo or screenshots you added.
