There's no magical "prompt time". The process's stdin's openness to
writing is not conditional.
Just send it all the input at once with the proper newlines in place
and it should work just fine assuming the user input was valid
(barring vpopmail using some fancy terminal input malarkey like
curses).

Cheers,
