I've wondered about this for years.  The easiest way _I_ can think of would be to add an option you can get to by r-clicking the sent folder (or one of the messages in it).

Can the header on the copies to Self folder show 'To' rather than 'From' as is the case on the Inbox header? I know that the listing in Copies to Self each start with 'To:' but a header that says 'To' would seem more appropriate.
