PHP IMAP收QQ邮件，SMTP存入另外QQ邮箱

作用，将qq1收到邮件，用qq2的账号、以qq0的为发件人身份放到qq2的邮箱。

什么样做这样一个功能，一个朋友要求的，她不告诉我为什么，好吧

<?php
define('USER','xxx@qq.com');//qq1用户名
define('PWD','xxx');//qq1密码
define('USER_RECEIVER', 'xxx@qq.com');//转发目标

define('REV_INTERVAL', 30);//收取间隔，单位：秒,不要太小否则可能导致邮箱被封
define('DELETE', false);//设置为false表示不删除,设置为true,转发后删除

define('DEBUG', false);
