Microsoft says that Office 365 will support internationalized email addresses (EAI) in Q1 2018.

Frankly, I doubt that. Given that the direct SMTP support for mail() is Windows specific (other systems always use an MTA such as sendmail, and that is possible on Windows as well), the moderate amount of work on the implementation[1], and the fact that implementing this in C is error-prone and unlikely to be much more efficient than a PHP implementation, it might be preferable to drop the implementation at all, in favor of userland libraries.

I tried some libraries (like PHPMailer), but many seems to not support it. Maybe the PHP native lib could lead the way in this matter? It would be great to have a native mail function supporting internationalization. I agree it is more a feature than a bug, though. Best regards ------------------------------------------------------------------------ [2021-11-15 11:05:38] cmb@php.net Changing to feature request per the comment above. ------------------------------------------------------------------------ [2021-11-12 11:44:25] heiglandreas@php.net According to https://php.net/mail the *to*-parameter "must comply with » RFC 2822". Which does not allow anything else than ASCII. As the SMTPUTF8 flag is defined in RFC6531 which is titled "SMTP Extension for Internationalized Email". Every client and server implementation can, but does not have to, implement it. So it is perfectly valid that the mail-function for windows so far does not support Internationalized Email. If you need that feature, check out one of the many mail-libraries on https://packagist.org ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
