# Domains & addresses

OpenEmail is built around the domain rather than the mailbox. You point one at us, and every address on it is real.

## In this section

- [Catch-all addresses](https://openemail.uk/docs/knowledge/addresses/catch-all.md): Every address on the domain receives, including ones that have never been created. One switch closes it.
- [Multiple domains](https://openemail.uk/docs/knowledge/addresses/domains.md): Point several domains at one inbox, subdomains included.
- [DMARC policy](https://openemail.uk/docs/knowledge/addresses/dmarc.md): A starter p=none record, printed to copy or written by a sync, never tightened for you.
- [Temporary addresses](https://openemail.uk/docs/knowledge/addresses/temp-address.md): An address that works for a fortnight and then stops, so a signup cannot follow you.
- [Send as any alias](https://openemail.uk/docs/knowledge/addresses/alias-send.md): Reply from the exact address the mail arrived on.
- [Merged inboxes](https://openemail.uk/docs/knowledge/addresses/merged.md): Read every address in one stream, or narrow to the two or three you actually work out of.
- [Forward an address elsewhere](https://openemail.uk/docs/knowledge/addresses/address-forwarding.md): Point any address, or everything a domain accepts, at an outside mailbox instead of this one.
- [Workspace branding](https://openemail.uk/docs/knowledge/addresses/workspace-brand.md): Put your own mark and logo in the sidebar, in place of ours.
