Email specifications

Business email DNS and security specification

Reliable business email depends on both mailbox-provider configuration and correct domain authentication records.

Routing

MX records tell other mail systems where the domain's incoming email is delivered.

Modern mail delivery increasingly depends on the domain proving which systems are authorised to send on its behalf.

DNS changes should take account of existing services before replacing records.
