# mailu

Mail — Mailu, with its provisioner (the `smtp` provision) and tools, on the tool runtime.

## Settings

A definition names no mesh (novox/hq ADR 0112, ADR 0155), so the values that are this
installation's are settings on the assignment, `settings set mailu <file>`:

```json
{"domain": "…", "sitename": "…", "website": "https://…", "proxy-address": "…"}
```

`domain` is the mail domain (also the provisioner's, for a consumer's address); `sitename` and
`website` are shown by the web front; `proxy-address` is what `REAL_IP_FROM` trusts a real-IP
header from — the address the proxy forwards with. The front's own hostname is the name of its
`web` route, told to it by the mesh.

## Files it does not know
