Japanese mobile operator NTT DoCoMo Inc is the first operator in the world to launch anti-spam protection for its mobile users. The company has announced that it will automatically start blocking all spam (unsolicited email advertising) for the users of its i-mode email services from later this year.
Under a new Japanese law, all spam email must contain the subject line mishodaku kokoku (which means unsolicited advertisement). DoCoMo will simply block i-mode email that contains this line. The company plans to start this on October 1, and customers can apply to opt back in by de-activating the service on the i-mode portal.
However, it remains to be seen how successful this will be, as the measures to restrict spam globally are proving far from easy implement, and many spammers simply ignore them.
