As far as I notice all human intervention you have is click the button.
But you can make it self click by calling Button1Click(self) from another method.

Not very sure what you mean by user intervention, Are you trying to use MAPI without showing the dialog?

Then why not just use TIdSMTP component
Much simpler to use and there are no dialogs, message is just sent straight to server

thanks ewangoya: top tip it works a treat using TIdSMTP. MAPI started outlook and required a send button press to work but this solution talks direct to the mail server.
