Inadvertently fixed the email notification function of comments

The comment email notification function has been disabled for a long time and has not been set up properly, whether it is a plug-in or the comment email notification function that comes with this topic.

Before using this theme, we used plug-ins and QQ mailbox to send notifications. However, the plug-ins will fail after changing to this joe theme. Later, the subject upgraded the comment email notification function, but it has not been set successfully.

Today, I suddenly found that the QQ email authorization code was filled in the Qinglong panel, which is required in the comment email notification settings of this topic! If you change the comment email notification setting of the subject to a normal QQ mailbox, it should work. After a try, it is.

The only drawback is that replies in the background will not trigger email notifications, but only replies on the article page.
