That you probably cannot do. You could try forging the address (make
sure you change the envelope sender as well as the From: line in your
mail), but I am suspecting that even so, the mail gateways will block
you. The envelope and header From: may appear to be ok, but since you're
connecting to a mail gateway via SMTP, it's they can tell it's not mail
from one of their own phones, and they probably check the address of the
connecting server in order to distinguish other keitai providers, if
they even use the same gateway.
