How can PHP classes or libraries be leveraged to streamline the process of handling undelivered emails?

Undelivered emails can be handled more efficiently by using PHP classes or libraries to manage and track email delivery status. One way to streamline this process is by utilizing libraries like PHPMailer or SwiftMailer, which provide features for handling bounced emails and tracking delivery statuses. 

// Using PHPMailer to handle undelivered emails

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php'; // Include PHPMailer autoload file

$mail = new PHPMailer(true);

try {
    // Set up the mail server settings
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'your_password';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    // Set the recipient email address
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    // Set the email content
    $mail->Subject = 'Test Email';
    $mail->Body = 'This is a test email';

    // Send the email
    $mail->send();

    echo 'Email sent successfully';
} catch (Exception $e) {
    echo 'Message could not be sent. Mailer Error: ' . $mail->ErrorInfo;
}
