Hi, I am using mailgun php sdk for sending mail with active domains of mailgun. Below is my php code for sending mail.

<?php

require 'vendor/autoload.php';

use Mailgun\Mailgun;

try {    
    $mg = Mailgun::create('[My Key]');
    $htmlMessage = '';

    print_r(
            $mg->messages()->send('[My Activated Domain]', [
                'from' => 'zakirali1991@gmail.com',
                'to' => 'hussainzakirali@gmail.com',
                'subject' => 'The PHP SDK is awesome!',
                'text' => 'It is so simple to send a message.'
                    ]
            )
    );
} catch (Exception $ex) {
    print_r($ex->getTrace());
    //print_r($mg);
}

The above code working fine when sending mail to "zakir@phonato.com" but when i am trying to send mail to "hussainzakirali@gmail.com, zakirali1991@gmail.com, zakir1991@yahoo.com" i am getting the error of "The parameters passed to the API were invalid. Check your inputs!"
