G.12. Changes from version -09 to -10
1. Changed uses of "character length" to "octet length" and
wrote a brief introduction
2. Modified text in Appendix A to permit extensions that would
permit non-ASCII characters in command arguments or replies.
3. Moved reference to RFC 1870 to Normative, since it is
referenced in a SHOULD.
4. Changed the description of MX handling using Glenn Anderson's
text. No substantive change, just clarity.

Title : Simple Mail Transfer Protocol

This document is a specification of the basic protocol for Internet
electronic mail transport. It consolidates, updates, and clarifies
several previous documents, making all or parts of most of them
obsolete. It covers the SMTP extension mechanisms and best practices
for the contemporary Internet, but does not provide details about
particular extensions. Although SMTP was designed as a mail
transport and delivery protocol, this specification also contains
information that is important to its use as a "mail submission"
protocol for "split-UA" mail reading systems and mobile environments.
