Toggle domain email forwarding

Enable or disable domain-level email forwarding and return the refreshed state. Get {id} from GET /api/v2/domains data[].id. Use this only for the domain-level forwarding integration. If the domain is attached to a shared-hosting account, prefer shared-hosting email forwarders; forcing domain-level routing can replace existing MX records and stop hosting mailboxes from receiving mail. Body accepts only enabled and optional force. force is valid only when enabling and tells the server to remove existing non-forwarding MX records before enabling routing.
