Type any name, get an address instantly. No signup, no password, no account to lose. Mail just shows up.
Type "blahblah" and you're reading mail sent to blahblah@yourdomain — no account, no login, ever.
Messages are auto-deleted after a set time, so nothing sensitive lingers around forever.
A single Node.js server handles SMTP receiving and the web UI. No Docker, no external services.
Messages are stored on disk with Node's built-in SQLite, so an app restart doesn't wipe every inbox.
