Abstract

Internet Message Access Protocol (IMAP) version 4rev1 has basic support for non-ASCII characters in mailbox names and search substrings. It also supports non-ASCII message headers and content encoded as specified by Multipurpose Internet Mail Extensions (MIME). This specification defines a collection of IMAP extensions that improve international support including language negotiation for international error text, translations for namespace prefixes, and comparator negotiation for search, sort, and thread.
