TOKYO-NTT DoCoMo Inc. announced it will limit the number of e-mail messages users can send to 1,000 per day, beginning Oct. 20. The company said the move is part of its ongoing efforts to counter the growing amount of spam being sent via its i-mode network and assumes that anyone sending a high volume of messages is a spammer.
In other efforts to reduce spam, the company said it has recently begun suspending or rescinding spammers’ subscriptions for all registered handsets in response to the increasing number of spam mail individual subscribers receive from mobile phones. So far the company said it has suspended contracts with several hundred subscribers who it has identified as spammers.
Spam is becoming an increasing problem for mobile communications users, and DoCoMo has been one of the most aggressive carriers in targeting the issue.
