How to Manage Domains

Domains define the email namespaces your mailserver handles. All addresses must belong to a configured domain. Only users with Admin role can add, edit, or delete domains; Domain Admins and regular users cannot.

Add a domain

  1. Log in to the management interface.
  2. Open Domain in the menu.
  3. Click Add Domain.
  4. Enter the domain name (e.g. example.com).
  5. Save.

The domain must be a valid domain name. It is available for users and aliases immediately.

Domain List

Delete a domain

  1. Open Domain in the menu.
  2. Select the domain to delete.
  3. Confirm the deletion.

Deleting a domain removes all associated users, aliases, and DKIM configuration. This cannot be undone. Back up data before deleting.

Changing a domain name

Changing the domain name is not supported. To use a different name, delete the domain and add a new one with the new name (and reconfigure users/aliases as needed).

For access control details, see User roles reference.
