WordPress comments email notification for authors

I’m admin of a question and answers website in WordPress. All users are defined like authors.

I have the problem that when I approve a comment ( an answer to a question), the author receives too much personal information ( email address, ip, whois arin, links of: spam it, trash it, approve it, ) of other users by the comments notification email sent by WordPress.

Is there a way to modify this email sent to authors?

The wp_notify_postauthor() function is pluggable meaning that you can copy the code and paste it into a plugin file or theme functions file keeping the same function name and WordPress will use your version rather than its own. Edit your version of the function to send as much or as little information as you like.
