It's been discussed many times before and I don't believe there is a 
currently a configuration option to change it.  It's added by the 
addReceivedHeader function in the Horde MIME library 
(MIME/Headers.php).  If you want to get rid of it from emails sent from 
IMP, comment out the addReceivedHeader call in the compose.php screen.  
There are likely other cases where it would be added (itip attachments, 
for instance).

Keep in mind that adding this header is normal mail client and MTA 
behaviour, which is why it exists in the Horde MIME library.  Send 
email from any client and you'll see that header is present.  It can be 
filtered out at the MTA level, which would be the proper place to do 
it, if you're concerned about any mail client on your network leaking 
this information.
