This document discusses 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 existing problems in the transition period
between IPv4 SMTP and IPv6 SMTP.  It also defines operational
requirements for stable IPv4/v6 SMTP operation.

This document does not define any new protocol.
