Error with email class in CI 3.1.8

./system/libraries/Form_validation.php

PHP Code:

    /**
     * Valid Email
     *
     * @param    string
     * @return    bool
     */
    public function valid_email($str)
    {
        if (function_exists('idn_to_ascii') && preg_match('#\A([^@]+)@(.+)\z#', $str, $matches))
        {
            $domain = defined('INTL_IDNA_VARIANT_UTS46')
                ? idn_to_ascii($matches[2], 0, INTL_IDNA_VARIANT_UTS46)
                : idn_to_ascii($matches[2]);
            $str = $matches[1].'@'.$domain;
        }

        return (bool) filter_var($str, FILTER_VALIDATE_EMAIL);
    } 


Now you can see that it is checking the email domain.

im using the same validation rule in another CI 3.1.5 and it works perfect. but i have this issue on my new project with CI 3.1.8 !

the domain of the entered email is @gmail.com and i tested with my @icloud.com email. but keep showing error that i must enter valid email address !

i have google it and some people reported this as a bug. is it a bug?

I'll try it later today on my internet providers smtp host comcast.

I just checked the CodeIgniter 3.1.5 version of the Form_validation class and it doe's not
check for the email domain like CodeIgniter 3.1.8 doe's.

So maybe that is what is causing your problem.

The form validation work. The error is in the code. Without the code, i can not help.
