Are there any best practices for incorporating PHPMailer into existing PHP code for handling email headers?

When incorporating PHPMailer into existing PHP code for handling email headers, it's important to ensure that the headers are correctly set to prevent email spoofing and improve email deliverability. One best practice is to use the PHPMailer library to handle email sending, as it provides built-in functionality for setting headers securely. 

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

require 'vendor/autoload.php';

// Create a new PHPMailer instance
$mail = new PHPMailer(true);

// Set the email headers
$mail->setFrom('from@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com', 'Recipient Name');
$mail->Subject = 'Subject of the email';
$mail->Body = 'Body of the email';

// Send the email
if (!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}
