Send a unique message is faster than send twice (twice for saving on IMAP server). Mail client can save message in 'pending message' folder, connect with MTA and MTA read and send this message, than mail client move message to 'Sent' folder. Send a URI is faster* than download the message and send to MTA (forward) (partially useful, a matter of habit: forward the big message and if necessary sent another mail with some text). *assuming a slow connection between MUA and servers (but not between MTA and IMAP server). Some improvement on IMAP protocol to create a message from another and prepending a content should make BURL more useful. -- Reinaldo de Carvalho
