In what ways can the PEAR-Mail package be utilized to enhance the security of PHP contact forms and prevent spamming?

One way to enhance the security of PHP contact forms and prevent spamming is by using the PEAR-Mail package to send form submissions to an email address. This can help prevent direct access to the email address from being exposed in the form's HTML code, reducing the likelihood of spam bots harvesting the email address for spam purposes. 

<?php
require_once "Mail.php";

$from = "Sender <sender@example.com>";
$to = "Recipient <recipient@example.com>";
$subject = "Contact Form Submission";
$body = "This is a test email";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
    'host' => 'smtp.example.com',
    'port' => '25',
    'auth' => true,
    'username' => 'username',
    'password' => 'password'
));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
    echo 'Error: ' . $mail->getMessage();
} else {
    echo 'Message sent successfully';
}
?>
