# Domain settings

> Understand domain-level inbound settings for sending and receiving domains.

The **Settings** section appears on sending & receiving domain detail pages. Sending-only domains hide these settings until receiving is enabled.

## Planned controls

| Control               | Purpose                                                      |
| --------------------- | ------------------------------------------------------------ |
| **Catch-all mailbox** | Route mail sent to any address on the domain to one mailbox. |
| **Default labels**    | Apply labels to every message received on the domain.        |
| **Webhook**           | Notify a URL when the domain receives a message.             |

## What to use now

* Create explicit mailboxes for each address you need.
* Use mailbox sender rules to allow or block inbound senders.
* Use domain sender rules through the Management API when one rule set should apply across every mailbox on a sending & receiving domain.
* Use team webhooks for delivery and inbound events.

## What happens next

More domain-level inbound controls will appear here as they become editable. Sending-only domains can be switched to sending & receiving from the domain detail page first.
