通过PHP脚本发送的邮件，则无需保存在“已发送邮件”邮箱中

Question

当通过PHP脚本使用SMTP发送邮件时，每次将邮件自动保存到已配置邮箱的“已发送邮件”文件夹中。但是这里不需要通过PHP脚本使用SMTP发送邮件时进行保存。任何帮助，不胜感激！

我的PHP SMTP代码如下：-

<?php
            $config['protocol'] = 'smtp';
            $config['smtp_host'] = 'smtp.office365.com';
            $config['smtp_port'] = '25';
            $config['smtp_port'] = '587';
            $config['smtp_timeout'] = '7';
            $config['smtp_crypto'] = 'tls';
            $config['smtp_user'] = 'user@user.com';
            $config['smtp_pass'] = 'password';
            $config['charset'] = "utf-8";
            $config['wordwrap'] = TRUE;
            $config['newline'] = "\r\n";
            $config['validation'] = TRUE;
            $config['mailtype'] = 'html';
            $cc_email = str_replace(';', ',', $mail_cc);
            $this->email->cc($cc_email);
             if (!empty($file)){
                    $this->email->attach($file);
                }
            $this->email->subject($_POST["subject"]);
            $this->email->message($message);
            $this->email->send();   
?>
