使用雅虎电子邮件地址帐户时无法发送消息

Question

我正在尝试从联系表单发送邮件以发送到Gmail地址帐户。我的问题是，当我使用雅虎电子邮件地址时，它不会向收件人发送gmail地址帐户但是当使用gmail地址帐户发送给收件人时，gmail地址帐户看起来很好..

像这样....

<?php
 if (isset($_POST['contact_name']) && isset($_POST['contact_email']) && isset($_POST['contact_num']) && isset($_POST['contact_text'])){
    $contact_name = $_POST['contact_name'];
    $contact_email = $_POST['contact_email'];
    $contact_num = $_POST['contact_num'];
    $contact_text = $_POST['contact_text'];
    if (!empty($contact_name) && !empty($contact_email) && !empty($contact_num) && !empty($contact_text)){
        $to = 'jeffgamasan@gmail.com,life1trading@gmail.com';
        $subject = 'Contact form submitted';
        $body = $contact_name."\n".$contact_text. "\n" .$contact_num;
        $headers = 'From: '.$contact_email;
    if (@mail($to, $subject, $body, $headers)){
       echo "<script>window.location.href='thankyou.php'</script>";

    }else{
        echo "<script>window.location.href='error.php'</script>";

    }

    }else{
        echo "<script>window.location.href='error.php'</script>";
    }
}
?>
