PHP 进行统一邮箱登陆的代理实现（swoole）

　　在工作的过程中，经常会有很多应用有发邮件的需求，这个时候需要在每个应用中配置smtp服务器。一旦公司调整了smtp服务器的配置，比如修改了密码等，这个时候对于维护的人员来说要逐一修改应用中smtp的配置。这样的情况虽然不多见，但遇上了还是很头痛的一件事情。

　　知道了问题，解决起来就有了方向。于是就有了自己开发一个简单的smtp代理的想法，这个代理主要的功能（参照问题）主要是：

　　　　1.接受指定IP应用的smtp请求；

　　　　2.应用不需要知道smtp的用户和密码；

　　　　3.转发应用的smtp请求。

　　开发的环境：Linux，php(swoole);

　　代码如下：
