My understanding of what this does. If the source email address
domain is hosted on the same box it just checks if it exists. If its
not hosted on the same box it just does a "dig domain mx". Is that
right? I assume it uses named which is running on the same box as an
authorative and caching name server. I have named/bind configured as
open to recursive lookups only to my IP pools and obviously open to
authorative from anyone.
