Description

This transform uses a special type of DNS Name - an MX record. It determines which other domains uses this DNS Name as an MX record. This is very useful in the infrastructure footprint of an organisation as it can reveal other domains that the organisation uses. If company X's Domain all have MX records pointing to a single DNS name this transform can find all (or most) of these domains.
