not everyone is on sendmail we're talking about adding 2 parameters, a return path and forward path. Hardly complex. this allows us to - not have to parse the headers - not have to re-write the entire message when stripping bcc these things are not cheap. they will affect service capacity. Why would you incur such penalty simply to avoid transmission of a couple of parameters? It's trivially simple for an MUA to supply this information when it wants to send the message. There's no reason to assume this information would be lost either. It's up to the server how to record such things and make them visible. Whether that's in the sent items folder or something associated with the message. Distinction between envelope and content is a key principle of SMTP. One could argue it's also a cause of certain issues, but I don't think it should be discarded without some fairly serious thought.
