It's a requirement for MTAs to add Received: headers as the mail  
passes through them to avoid mailing loops.  Trying to subvert this  
is a bad idea...

Normally, your mail client will keep track of all Sent messages if  
you configure it properly.  That's a better choice than having the  
MTA do it, but you can look into the content_filter mechanism to  
archive mail which passes through if you really want to do so.
