This document talks about SMTP operational experiences in IPv4/v6 dual
stack environments.  As IPv6-capable SMTP servers are deployed, it has
become apparent that certain configurations of MX records are necessary
for stable dual-stack (IPv4 and IPv6) SMTP operation.  This document
clarifies the problems that exist in the transition period between IPv4
SMTP and IPv6 SMTP.  It also defines operational requirements for stable
IPv4/v6 SMTP operation.

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
