Title : Marking Mail Transfer Agents in Reverse DNS with TXT RRs

In contrast to other more extensive approaches to deal with
unsolicited email, commonly called "spam", this memo discusses a very
simple authentication scheme. It uses marking of hosts in reverse
DNS (IN-ADDR.ARPA and IP6.ARPA zones) to allow the receiving mail
transfer agents to decide whether the connecting (sending) host is a
designated mail transfer agent (MTA) or not.
Despite being a weaker scheme than most of the other proposals
currently discussed, it can reduce the amount of spam and viruses/
worms significantly and has the advantage that it can be implemented
based on existing and well-established Internet technology like DNS
without any changes to that technology.

Group (ASRG) of the IRTF.

In the body type:
"FILE /internet-drafts/draft-stumpf-dns-mtamark-04.txt".
NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
