[EAI] ascii at UTF-8 and ascii at Punycode

[fujiwara at jprs.co.jp]

Is ASCII at UTF-8 equal to ASCII at Punycode ?

I prepared UTF8SMTP Email address: fujiwara@ U+65E5 U+672C U+8A9E .dnslab.jp.

MX resolution for fujiwara@ U+65E5 U+672C U+8A9E .dnslab.jp results
the same SMTP server for XN--WGV71A119E.dnslab.jp, but the SMTP server
can be configured to reject "fujiwara at XN--WGV71A119E.dnslab.jp".

I should accept "fujiwara at XN--WGV71A119E.dnslab.jp" ?

Currently, I allow both addresses.

Regards,
