i tested with https://docs.mybb.com/1.8/faq/mail/

but it show PHP could not send the mail

its your Hosting Provider problem look like your provider blocked php mail on your account you can try using SMTP mail through targethero, maichimp, etc.

I saw in https://docs.mybb.com/1.8/faq/mail/

edit the file inc/functions.php to try a workaround fix.

Find: php mail($to, $subject, $message, $headers);

Add before: php ini_set("sendmail_from", "[email protected]");

The final result of the edit should be: php ini_set("sendmail_from", "[email protected]"); mail($to, $subject, $message, $headers);

YOURDOMAIN in the above code must be replaced by the domain where the forum is hosted.
============
Where to add YOURDOMAIN?
