I currently use Mail::RFC822::Address to validate email addresses given to us on a web form.

Given that IDN registrations are now being permitted, what do I need to do to accept international domain names?

Am I supposed to convert them to punycode first, then pass them to validate, or do I need a newer validator? Is there a newer one?

Should I store them as IDN or in the punycode form?

Do I use them to send mail in IDN format or punycode format? I use Net::SMTP if that matters.

Thanks for any help and guidance.
