True about re-working the query.  As for the second part - we do have 
to obtain the MIME structures of all messages (which would include the 
Message-IDs) if we are doing message previews for all messages in the 
mailbox, so in that particular situation this additional query would 
add little overhead.  If we implement this additional query in the full 
preview situation, maybe we can note in the preferences that selecting 
Previews for all messages will also give you the ability to indicate 
replies/forwards in the mailbox screen.
