<?php
                            
                            // phpmailer--multi-recipient-example.php
                            // Inject multiple test messages into Kasplo Engine using PHPMailer 
                            
                            // Use PHPMailer
                            require_once('/usr/share/php/PHPMailer/class.phpmailer.php');
                            require_once('/usr/share/php/PHPMailer/class.smtp.php');
