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 zone) to allow the receiving mail transfer agents to
   decide whether the connecting (sending) host is a designated mail
   transfer agent (MTA) or not.

In the body type:

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.
