Comment-Emailer allows you to customize the email wordpress automatically sends when a new comment, pingback or trackback has been approved. With Commented-Emailer you can change the sending email address, message body, and enable or disable all of the default options such as including the authors name, ipaddress, website, comment or reply to address.

After installation you will have a new tab under settings that will give you access to change just about every access of your auto generated emails. Just make sure you enable Commented-Emailer
