最近 Disqus 被某国的墙搞的十分不稳定，于是又用回了 WordPress 自带的评论系统，但是这个评论系统却不带评论者被回复时的邮件提醒。我有自己的发信服务器（AWS SES）系统，所以理论上可以配合插件实现这个效果。但是我看了很多插件，基本上操作页面都太复杂，而且回复的邮件通常不支持中文，我只需要一个简单的回复系统，不用那么麻烦，于是干脆自己开发一个，最终比较完美的实现了这个功能。
我开发的这个功能特点是：当评论者被回复时，邮件标题是 “Re: [文章标题]”，这样评论者的一个留言被多个人回复时，会被自动在本地邮件客户端上归为一类；而且评论者收到邮件后可以直接回复邮件，会直接给回复的发出者发邮件（不会显示在网站上，我也无法看到，这将是两人的私聊）。
