Originally, email addresses were ASCII-only. An email address consists of a
"localpart", an "@" and a domain name. Only ASCII was allowed in message
headers. With internationalized email, localparts can be in UTF-8, domains can
use internationalized domain names (IDN/IDNA: unicode names with both an UTF-8
encoding, and an ASCII encoding for use in DNS with domains starting with
"xn--"), and message headers are allowed to contain UTF-8 as well.
headers. With internationalized email (EIA), localparts can be in UTF-8, domains
can use internationalized domain names (IDN/IDNA: unicode names with both an
UTF-8 encoding, and an ASCII encoding for use in DNS with domains starting with
"xn--"), and message headers are allowed to contain UTF-8 as well. The SMTPUTF8
extension allows transferring internationalized messages. The IMAP UTF8=ACCEPT
extension provides access to the messages.
With internationalized email, users of scripts not representable in ASCII can
use their native scripts for their email addresses.
