# Mail

> A client-first design is in development: connect your existing mailbox before you consider running your own mail server

<Info>
  Evidence state (2026-09-24, v0.41.0): Mail is `in development`. The release
  catalog declares a Stalwart Mail Server component with a recorded mail
  domain setting, but the current release does not install it. There is no
  executable Mail workload yet. This page describes the design direction,
  not something you can set up today.
</Info>

Mail is not installable yet. The design direction is client-first: you connect an existing mailbox before you consider running your own mail server, and the two decisions stay independent of each other.

## Planned design

| Experience                  | What it means                                                                                                                        | Status                                   |
| --------------------------- | ------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------- |
| Connect an existing mailbox | Use a self-hosted webmail client with your current provider's IMAP/SMTP or supported login, without operating mail delivery yourself | Planned                                  |
| Run your own mail server    | Operate your own domain's mail delivery with Stalwart, or an integrated suite such as mailcow                                        | Declared in the catalog; not installable |

Selecting Mail is planned to never make DNS or MX changes, open a public SMTP listener, or send anything on your behalf without an explicit, separate approval step. Running your own mail server is planned as an opt-in for households that want to operate their own domain, not a requirement for using a mail client with an account you already have.

## What exists today

The release catalog declares a `mail` use case with the Stalwart Mail Server component and one recorded setting: your mail domain. Recorded means the setting is captured for a later release to apply. The current release does not install or configure Stalwart, and there is nothing to select, generate, or apply for Mail yet.

## What to expect

* A client-first flow comes before any self-hosted mail-server requirement.
* Sending a real message will need an explicit, separate approval step.
* An own mail server or suite, when it ships, will be an additional opt-in, not a replacement for using the mailbox you already have.
