Mail to the address goes to the account, which may also send from it unless `send_enabled` is false. For a whole domain, that is every address there without a mailbox or entry of its own. Giving an address that is already routed moves it to the new account.

## Parameters

| Name | In | Required | What it is | Example |
|---|---|---|---|---|
| `source_pattern` | body | yes | An exact address, or `@` and a domain for the whole domain. | `sales@example.com` |
| `destination` | body | yes | The account it goes to. It isn't checked, so make sure it is a real one. | `you@example.com` |
| `send_enabled` | body | no | Whether the account may send from it. true if left out. |  |

## Good to know

- A domain that isn't listed yet is added, with a DNS zone but with mail off. The account can send from it, but mail sent to it arrives only once mail is turned on (Change a domain's settings).
- If that DNS zone can't be created, the answer is 502 and nothing is added.
