Overview and Framework for Internationalized Email
RFC 6530, “Overview and Framework for Internationalized Email”, is a Proposed Standard document published in February 2012 by J. Klensin, Y. Ko. It obsoletes RFC 4952, RFC 5504, RFC 5825. The canonical text is published by the RFC Editor.
Abstract
Full use of electronic mail throughout the world requires that (subject to other constraints) people be able to use close variations on their own names (written correctly in their own languages and scripts) as mailbox names in email addresses. This document introduces a series of specifications that define mechanisms and protocol extensions needed to fully support internationalized email addresses. These changes include an SMTP extension and extension of email header syntax to accommodate UTF-8 data. The document set also includes discussion of key assumptions and issues in deploying fully internationalized email. This document is a replacement for RFC 4952; it reflects additional issues identified since that document was published. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
