        Title           : A NULL MX Resource Record for Domains that Accept No Mail

Abstract:
   Internet mail determines the address of a receiving server through
   the DNS, first by looking for an MX record and then by looking for an
   A/AAAA record as a fallback.  Unfortunately this means that the A/
   AAAA record is taken to be mail server address even when that address
   does not accept mail.  The NULL MX RR formalizes the existing
   mechanism by which a domain announces that it accepts no mail, which
   permits significant operational efficiencies.
