It should already be there at least in 2.7.4 which is stable unless 
you've really tweaked your main.cf. I'd run a postconf | grep 
enable_orig and see if it's not set to yes.

enable_original_recipient (default: yes)

     Enable support for the X-Original-To message header. This header is 
needed for multi-recipient mailboxes.

     When this parameter is set to yes, the cleanup(8) daemon performs 
duplicate elimination on distinct pairs of (original recipient, 
rewritten recipient), and generates non-empty original recipient queue 
file records.

     When this parameter is set to no, the cleanup(8) daemon performs 
duplicate elimination on the rewritten recipient address only, and 
generates empty original recipient queue file records.

     This feature is available in Postfix 2.1 and later. With Postfix 
version 2.0, support for the X-Original-To message header is always 
turned on. Postfix versions before 2.0 have no support for the 
X-Original-To message header.
