What are the benefits and drawbacks of using pre-existing open source mail clients compared to creating a custom solution in PHP?

When deciding between using pre-existing open source mail clients or creating a custom solution in PHP, the benefits of using pre-existing clients include saving time and effort in development, leveraging the expertise of the open source community, and having access to a wide range of features and functionalities. However, drawbacks may include limitations in customization and flexibility, potential security vulnerabilities if not properly maintained, and the need to adhere to the license terms of the open source software. 

// Example PHP code snippet for sending an email using the PHPMailer library
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;

require 'vendor/autoload.php';

$mail = new PHPMailer(true);

try {
    $mail->isSMTP();
    $mail->Host = 'smtp.example.com';
    $mail->SMTPAuth = true;
    $mail->Username = 'your@example.com';
    $mail->Password = 'yourpassword';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;

    $mail->setFrom('from@example.com', 'Your Name');
    $mail->addAddress('recipient@example.com', 'Recipient Name');

    $mail->isHTML(true);
    $mail->Subject = 'Subject';
    $mail->Body = 'Email body here';

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