When replying to request CC is populated with the "sent to" address.

We use a number of email address that forward to SDP. The send to addresses ae distribution groups that contain the SDP mailbox as a member. We use this so that we can assign "send to" address to different groups in SDP.
 
When we reply to a request, the CC field is populated with the original send to address. Is there anyhing we can do to stop this?
