Shevet HaKehosi - Sending A Fax Across The Shabbos Border?

May a person send a fax on Motzae'i Shabbos from Eretz Yisrael to the U.S. where it is still Shabbos? The Shevet ha'Kehosi says that it is permitted. However, if you have reason to suspect that the intended recipient will look at the fax while it is still Shabbos it is forbidden to send him the fax, because it is forbidden for the recipient to look at a fax that he receives on Shabbos.
