Unless RFC 974 has been superceeded :
It is possible that the list of MXs in the response to the query will be empty. This is a special case. If the list is empty, mailers should treat it as if it contained one RR, an MX RR with a preference value of 0, and a host name of REMOTE. (I.e., REMOTE is its only MX). In addition, the mailer should do no further processing on the list, but should attempt to deliver the message to REMOTE. The idea here is that if a domain fails to advertise any information about a particular name we will give it the benefit of the doubt and attempt delivery.
