No email notification on neither new entry nor reply

Hi,

As per title, I just installed EasyBook Reloaded in my Joomla 1.7 site. So far, it's been a great experience. I really like it a lot. Well done, guys!

However, I have one missing feature. I, as an admin, don't get any email notification on new guestbook entry. And, when I tried to give a reply, no email notification. Can you help me on this matter?
FYI, I just transfer my domain to a new domain. Initially, when I was still in my old domain, I received email notification for new guestbook entry.
Just in case, this info is anything help.

Thank you.
