To get bounced emails in CakePHP, you need to follow these steps:

1. Configure the email component in your CakePHP application. Open the app.php file located in the config folder and make sure you have the following settings configured:

'EmailTransport' => [
    'default' => [
        'className' => 'Smtp',
        'host' => 'your-smtp-host',
        'port' => 25,
        'timeout' => 30,
        'username' => 'your-username',
        'password' => 'your-password',
        'client' => null,
        'tls' => null,
    ],
],
'Email' => [
    'default' => [
        'transport' => 'default',
        'from' => '[email protected]',
        'charset' => 'utf-8',
        'headerCharset' => 'utf-8',
    ],
],

1. Configure the bounce email address. Edit your EmailComponent class and include the following code:

1
2

$this->Email->emailFormat('both');
$this->Email->returnPath('[email protected]');

1. Handle bounced emails. When an email bounces, your bounce email address will receive a notification. You can create a controller action to handle these bounced emails. In this action, you can parse the email content to extract relevant information and update your database accordingly. Here is a simplified example:

1

3
4

6

public function handleBounce() {
    $emailContent = $this->request->data['message'];
    
    // Parse the email content to extract the relevant information
    // Update your database accordingly
}

1. Set up a webhook or cron job. Depending on the email service provider you are using, you may need to set up a webhook or a cron job to automatically call the handleBounce() action and process bounced emails.

Note: The specific steps may vary depending on your CakePHP version and email service provider configuration, but these steps provide a basic guideline to get you started.
