Vodafone Introduces Additional Anti-spam Measure

Vodafone K.K. has announced a new function will be introduced starting 30 March that blocks so-called “spoof mails”, mails sent via a PC with addresses posing as mobile handset mail addresses. With the new anti-spam measure, Vodafone K.K. aims to make its Vodafone live! mobile Internet service more dependable for customers. The spoof mail blocking function makes it possible to refuse mails sent via a PC that pose as mail addresses of Vodafone K.K., other mobile operator, or PHS^{Note 1} handsets. By accessing the Custom Mail Set-up page from either Vodafone live! or the Vodafone K.K. website (www.vodafone.jp), customers can select from the “accept (default setting)” or “refuse” settings to filter spoof mails. 

In addition, to distinguish spoof mail from legitimate mail as part of “forwarding and mailing list^{Note 2} services” offered by Internet service providers, customers can register forwarding and mailing list addresses to an “exempt list” in order to refuse spoof mails and receive forwarded and mailing list mails.^{Note 3}

Both the URL mail blocking function announced on 15 February and the spoof mail blocking function will be introduced simultaneously on 30 March. Vodafone K.K. will continue its efforts in taking measures to prevent spam to make Vodafone live! more comfortable for its customers.

Notes:

1. PHS applies to Willcom (formerly DDI Pocket) service only.
2. A system that allows participating members to receive the same mail using Internet mail.
3. Some mails from forwarding services or mailing lists may not be received even if registered on an “exempt list”.
