# Rail-Mail

Mail between machines, with a record that outlives the machines.

## Status
- **The rail itself** — Messages move; every one is a plain, readable file (`LIVE`)
- **The doorbell** — A note lands, the recipient is told — no human relay (`PROVEN`)
- **Public product** — Running in-house. Not open to sign-ups yet. (`NOT YET`)
