Mailgun API 仅适用于一封电子邮件

Question

我正在使用 PHP 和 Mailgun API 制作电子邮件订阅表格，但我只收到电子邮件到我在 mailgun.com 上用于创建帐户的主要电子邮件地址。当我用该电子邮件填写表格时，我会收到确认信，但它不适用于其他电子邮件。为什么会这样？这是代码：

初始化文件：

<?php
require_once 'vendor/autoload.php';

define('MAILGUN_KEY', 'key-2ce40f5e23c90b0d666f3e....');
define('MAILGUN_PUBKEY', 'pubkey-8cf7125996....');

define('MAILGUN_DOMAIN', 'sandboxc03eaee7674c4a9094ffa8d61845ddf5.mailgun.org');
define('MAILING_LIST', 'audimas@sandboxc03eaee7674c4a9094ffa8d61845ddf5.mailgun.org');
define('MAILGUN_SECRET', '...');

$mailgun = new Mailgun\Mailgun(MAILGUN_KEY);
$mailgunValidate = new Mailgun\Mailgun(MAILGUN_PUBKEY);
$mailgunOptIn = $mailgun->OptInHandler();
 ?>

主 index.php 文件：

<?php
require_once 'init.php';


if(isset($_POST['name'], $_POST['email']))
{
    $name = $_POST['name'];
    $email = $_POST['email'];

    $validate = $mailgunValidate->get('address/validate', [
        'address' => $email
    ])->http_response_body;

    if($validate->is_valid)
    {
        $hash = $mailgunOptIn->generateHash(MAILING_LIST, MAILGUN_SECRET, $email);

        $mailgun->sendMessage(MAILGUN_DOMAIN, [
            'from'      => 'noreply@audimas.com',
            'to'            => $email,
            'subject'   => 'Please confirm your subscription to us',
            'html'      => "Hello {$name}<br><br>You signed up to our mailing list. Please confirm below"
        ]);

        $mailgun->post('lists/' . MAILING_LIST . '/members', [
            'name'              => $name,
            'address'               => $email,
            'subscribed'    => 'no'
        ]);

        header('Location: http://localhost:8888/exam/index.php');
    }

}
?>

您正在使用sandboxc03eaee7674c4a9094ffa8d61845ddf5.mailgun.orgSandbox 子域发送电子邮件。

您应该收到如下错误：

Error: Sandbox subdomains are for test purposes only. Please add your own domain or add the address to authorized recipients in Account Settings.

要发送多封电子邮件，您必须首先创建自己的域。您可以从这里创建域

确保您的域名已验证。如果您的域名未经验证，您将收到如下错误：

Error: The domain is unverified and requires DNS configuration. Log in to your control panel to view required DNS records.
