Connect a mailbox

Open Settings, Connections. IMAP works with any provider and needs no extra setup.

Google and Microsoft need an OAuth client of your own:

• Google: set GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET. The redirect URI is https://your-domain/api/auth/callback/google.
• Microsoft: set MICROSOFT_CLIENT_ID and MICROSOFT_CLIENT_SECRET. The redirect URI is https://your-domain/api/auth/callback/microsoft.

Add the variables to deploy/.env, then run docker compose up -d in the deploy folder. The mailbox sync runs every five minutes inside the API. MAILBOX_SYNC_INTERVAL_MS changes that.
