 A Rust implementation of the [Smol Mail](https://code.randogoth.com/randogoth/smolmail) server: a minimalist, end-to-end encrypted mail protocol over a Noise-secured TCP connection, with an optional Reticulum (RNS) mesh carrier behind the `rns` build feature. `bunshin` implements the server side only — receiving, storing and serving sealed mail — not the client.
