How can the use of a Mailer class in PHP improve the security and reliability of sending emails compared to using the mail() function?

Using a Mailer class in PHP can improve security and reliability when sending emails compared to using the mail() function by abstracting the email sending process and providing methods for handling email headers, attachments, and other features. The Mailer class can also utilize SMTP authentication for secure email delivery and handle errors more effectively, providing better feedback in case of failures. 

<?php
// Include the Mailer class
require_once 'path/to/Mailer.php';

// Create a new instance of the Mailer class
$mailer = new Mailer();

// Set the email details
$mailer->setFrom('sender@example.com', 'Sender Name');
$mailer->addTo('recipient@example.com', 'Recipient Name');
$mailer->setSubject('Test Email');
$mailer->setBody('This is a test email.');

// Send the email using SMTP authentication
$mailer->send('smtp.example.com', 'username', 'password');
?>
