Re: [idn] IDN security and ACE leakage

I believe IDN is not only for local use, but also
for international exchange of identities and infor-
mations. I  believe most of them will surely use 
only IDN email addresses.

Enforcing dual email addresses 
(one using LDH domain and the other using IDN ) 
may be a (costly) remedy for such situations.

How can we enforce them?  Is it possible ?
How can they decide when and to whom they
should choose IDN email addresses over LDH ones?

They may   inadvertently or intentionally 
send emails using their Arabic email addresses 
while email contents are  in english or japanese.
