Title : A "Null MX" No Service Resource Record for Domains that Accept No Mail
Authors : John Levine
Mark Delany
Filename : draft-ietf-appsawg-nullmx-06.txt
Pages : 6
Date : 2014-07-25
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 no service MX RR, informally called null
MX, formalizes the existing mechanism by which a domain announces
that it accepts no mail, without having to provide a mail server,
which permits significant operational efficiencies.
