Hello,
Section 6.3 of draft-crocker-email-arch is about
Internationalization. Quoting the draft:
"Because its origins date back to the use of ASCII, Internet Mail has
had an ongoing challenge to support the wide range of necessary
international data representations. For a discussion of this topic,
see [MAIL-I18N]."
MAIL-I18N is a report on "Using International Characters in Internet
Mail" published in 1998. There is an existing IETF WG working on
email internationalization. The EAI WG published a SMTP Extension
for Internationalized Email Addresses as an Experimental RFC and
there are some existing implementations. I don't think that it is
worth referencing MAIL-I18N when there is newer work in the area of
email internationalization.
I suggest having the following for Section 6.3 with appropriate
references to RFC 5336.
Because its origins date back to the use of ASCII, Internet Mail has
had an ongoing challenge to support the wide range of necessary
international data representations. RFC 5336 specifies an SMTP
extension, as an Experimental Protocol, for transport and delivery
of email messages with internationalized email addresses or header
information.
There is an issue in that it is an Experimental Protocol and it may
not belong in a document about the existing Internet Mail
architecture. The alternative is to mention the ongoing EAI work to
standardize internationalized email.
Could you please comment about this?
Regards,
