MX API

Mail exchange records for a domain.

Mail exchange records for a domain. Each row is a priority and host, sorted the way mailers try them.

Empty mx means no mail exchanger. That is an answer, not an error. Lookups refresh on use. A day-old copy serves immediately while DNS is re-checked.

To check if a domain is free to register, use Domain.
