This document defines a new name form for inclusion in the otherName field of an X.509 Subject Alternative Name and Issuer Alternative Name extension that allows a certificate subject to be associated with an internationalized email address.

This document updates RFC 5280.

This specification extends the Internet Message Access Protocol (IMAP) to support UTF-8 encoded international characters in user names, mail addresses, and message headers. This specification replaces RFC 5738.

This document describes considerations for mailing lists with the introduction of internationalized email addresses.

This document makes some specific recommendations on how mailing lists should act in various situations. This document defines an Experimental Protocol for the Internet community.

This document describes a method for displaying downgraded messages that originally contained internationalized email addresses or internationalized header fields. This document defines an Experimental Protocol for the Internet community.

This specification extends the Internet Message Access Protocol version 4rev1 (IMAP4rev1) to support UTF-8 encoded international characters in user names, mail addresses, and message headers. This document defines an Experimental Protocol for the Internet community.

This specification extends the Post Office Protocol version 3 (POP3) to support un-encoded international characters in user names, passwords, mail addresses, message headers, and protocol-level textual error strings. This document defines an Experimental Protocol for the Internet community.

Traditional mail systems handle only ASCII characters in SMTP envelope and mail header fields. The Email Address Internationalization (UTF8SMTP) extension allows UTF-8 characters in SMTP envelope and mail header fields. To avoid rejecting internationalized email messages when a server in the delivery path does not support the UTF8SMTP extension, some sort of converting mechanism is required. This document describes a downgrading mechanism for Email Address Internationalization. Note that this is a way to downgrade, not tunnel. There is no associated up-conversion mechanism, although internationalized email clients might use original internationalized addresses or other data when displaying or replying to downgraded messages. This memo defines an Experimental Protocol for the Internet community.

Full internationalization of electronic mail requires not only the capabilities to transmit non-ASCII content, to encode selected information in specific header fields, and to use non-ASCII characters in envelope addresses. It also requires being able to express those addresses and the information based on them in mail header fields. This document specifies an experimental variant of Internet mail that permits the use of Unicode encoded in UTF-8, rather than ASCII, as the base form for Internet email header field. This form is permitted in transmission only if authorized by an SMTP extension, as specified in an associated specification. This specification Updates section 6.4 of RFC 2045 to conform with the requirements. This memo defines an Experimental Protocol for the Internet community.

This document specifies an SMTP extension for transport and delivery of email messages with internationalized email addresses or header information. Communication with systems that do not implement this specification is specified in another document. This document updates some syntaxes and rules defined in RFC 2821 and RFC 2822, and has some material updating RFC 4952This memo defines an Experimental Protocol for the Internet community.

Delivery status notifications (DSNs) are critical to the correct operation of an email system. However, the existing Draft Standards (RFC 3461, RFC 3462, RFC 3464) are presently limited to US-ASCII text in the machine-readable portions of the protocol. This specification adds a new address type for international email addresses so an original recipient address with non-US-ASCII characters can be correctly preserved even after downgrading. This also provides updated content return media types for delivery status notifications and message disposition notifications to support use of the new address type.

This document experimentally extends RFC 3461, RFC 3464, and RFC 3798. This memo defines an Experimental Protocol for the Internet community.

Full use of electronic mail throughout the world requires that people be able to use 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 memo provides information for the Internet community.
