WordPress 评论回复邮件通知插件 Comment Email Reply

今天下午登陆网站无意发现网站的邮件功能失效了，毫无疑问，最近这段时间的评论回复邮件没能发出去。问题很快被找到，原来是 WP Mail SMTP 插件被重置了，重新做了设置，又把当前在用的评论回复邮件通知插件 Comment Email Reply 做了一番改动

改动内容

使之兼容最新版的 WordPress，原插件已不能在新版的 WP 上正常工作了；
评论回复通知邮件延迟发送，默认延迟 300 秒；
将评论设置为 spam 或删除评论时也会向原评论人发送通知邮件；

使用方法

请确认网站的邮件功能正常，可借助于 WP Mail SMTP 插件来实现邮件功能
将下方代码复制并保存为 php 后缀文件，如 comment_email_reply.php
在网站目录 wp-content/plugins 下新建一个文件夹，如 Comment Email Reply，将上一步所建的 php 文件放入其中
登陆网站后台，在插件页面激活插件 Comment Email Reply 即可

以下是修改后的代码：
