$phpmailer->Username = "[email protected]"; //邮箱的登录账号
$phpmailer->Password = "*******"; //邮箱的登录密码 QQ邮箱为SMTP的授权码
$phpmailer->SMTPAuth = true; //启用SMTP认证
$phpmailer->SMTPSecure = 'ssl'; //SMTP加密方式（是否通过 ssl 连接，如果端口为25,则此处将"ssl"改为空白即""，否则不必改动）
$phpmailer->From = "[email protected]"; //发件人的地址（建议与登录帐号保存一致，不一致会邮箱会显示代发）
