The global nature of the DNS database means that you could not keep your
"outgoing MX" records private if you are directly on the Internet.  The
only time you can safely create bogus MX records (or any other type, for
that matter) is when you do not have IP connectivity to the rest of the
Internet, such as is often the case with TCP/IP LANs that are connected
to the rest of the world via UUCP.  In this case, you can have your own
root server and have an MX record direct "*." wherever you want. 

The DNS is for public data.  Private routing data must go somewhere
else, such as sendmail.cf.
