It will be much faster to get back the previous page than to go at the server to get it. But, if you think that is really required, we can add one. It would simply go back to the message I guess.

Well, it's not a big deal. If you think it's not consistent with the rest of application, then the Cancel button is not important. I can use Back button.

There probably should be a check on this form, saying "Don't send message content" (or something similar). It would be unchecked by default. So, if I don't want to send a message content, I'll check this checkbox.
