Replied to a topic by inee › DNS › 不知道是否有本地DNS做到这个功能？

@inee 之前做过一个本地dns代理，可以支持多个外部dns同时查询，并且以第一个为准。如果两个都哟返回结果不一样，会用优先选用第一个。[https://github.com/code4craft/blackhole](https://github.com/code4craft/blackhole)

但是dns查找只是一小步，操作系统本身也有缓存，实际上最终有较大影响的还是你要访问的站点的速度，如果混用dns造成CDN不生效我觉得是得不偿失的。

Replied to a topic by meteor2013 › PHP › 折磨了好几天了。用PHP的原生的mail()发邮件，显示发送成功。就是收不到

程序内调用的话，应该也是用SMTP协议发送(不清楚PHP，但是如果之前发送收到了，那应该就是对的)，跟本地搭建MTA的效果差距不大。
SMTP本身不复杂，但是邮件运营方的过滤策略就比较复杂了。抛开内容不谈，大的运营商都会根据发信IP进行过滤，你可以在gmail里选一封邮件，显示原始邮件，`Received: from`一栏就能说明问题了。你这样的邮件很可能已经被gmail拒收了。
你可以本地搭建一个接收服务器(postfix之类的)，然后测试一下。

@tititake 嗯，Java没法接触底层的东西，不过DNS在应用层，还算是可以处理的范围。

其实写的时候是把它当成一个Web服务器的架构来写的，参考了一些Jetty的设计。以后会更偏重处理逻辑吧，比如所有配置文件都是修改即生效，还有能够根据客户端IP来进行不同的DNS解析，这算是一个不同么？呵呵。

Replied to a topic by code4craft › 分享创造 › [发布]Java实现的DNS服务器BlackHoleJ

@tititake 呃，其实写BlackHoleJ之前不知道pdnsd...

看了一下，pdnsd功能很强大，还有uptest这些，毕竟10年了嘛，占用资源也少(我测试下来只有几百K)，但是配置稍微繁琐一点，一个DNS cache还要google一番是比较费劲的。

BlackHoleJ设计就是给懒人用的，比如你想自建一个防DNS污染的东东，又在公司内网，有些地址需要拦截，使用BlackHoleJ只需要把公司内网DNS配到第一个就可以了，就一行配置。

BlackHoleJ防污染用的是UDP+持久化污染地址黑名单，理论上比TCP快。

性能上我比较了下，两个响应都在0ms以下，pdnsd好像直接用的文件缓存，BlackHoleJ用了内存缓存，关闭时才持久化。qps分别是18000和50000，不过好像也没什么意义，都够用了。

其实最重要的，本来也是学习的态度做的这个，跟一个维护了10年的项目也没啥可比性。至于重复造轮子，见仁见智了，毕竟也没人用Java写过这个嘛。
