how to automaticly reply to sender at the same time while replying to group?

Hi,

In our country,newsgroup never encode the sender's email.So I can reply to 
sender by click the "Reply" button. But usually we choose to "Reply Group". 
Now, I want to do these two actions at the same time: let my Fidolook send a 
copy of my reply to the sender's mailbox when I reply to group,and without 
any extra operation.

how to?
