	Title           : Downgrading mechanism for Email Address Internationalization

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 bouncing
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.
