I am now using comment-reply-notification plugin, and it never sents me any email notifying that my comments are being replied. Can anyone tell me how the plug-in works?
An other problem is about the system mail, although I've changed my domain MX record to Google App account, and I can send email to Google Account, mails from my blog is always appears in my hosting server.(And the reason that I use Google App is that I cannot receive any mail on my hosting server except my blog's automatic mails)
It is very weird when I am testing the "reply-notification" function(Log out, write comment, and then log in, reply to that comment) and in the wrong mailbox I receive only one system email that notifies me someone comments to your post.
