I was afraid this argument was going to get started again... :-)

The problem with FCC is that the message you're saving is usually
missing some headers.  One of these, Message-ID, is significant
if you ever want to use the IDs to index the old messages.  It's
better to save the copy of the message that the MTA sends you.
It will have all the proper headers added.
