I don't understand the requirements. You want to duplicate mail? DNS can
*route* mail to servers via MX records, but it can't specify duplication.
With MX records, you can specify that mail should be delivered to one server
if another is down, or that a server should be picked at random from a list
of servers (for load-balancing), but MX-capable mail servers will still only
deliver the message *once*, not to every server in the MX list.

Or, maybe you meant something else by "duplicated"??
