Key RFCs for internationalized email addresses specify the basic
protocols for using them. The SMTP client can only know the SMTP
server's ability by EHLO command. In order to help the
internationalized email address delivery, this document suggests to
add the new DNS RR type for internationalized email protocols.
Through this RR type, the SMTP client can know whether the
destination SMTP server can support the SMTPUTF8 ability before
sending the EHLO command to the server.
