The Internet Society of China (ISC) released a blacklist of 112 IP addresses of spam servers yesterday.

Thirty-nine are located on the Chinese mainland, including 18 in Guangdong, another 13 come from Taiwan and two from Hong Kong. The list of IP addresses is the sixth part of the blacklist by ISC to fight against spam, and can be found and downloaded at www.isc.org.cn.

ISC will monitor and urge all the blacklisted mail service providers to deal with their junk mail before Oct. 29. Statistics show that in China, 60.5% of all e-mails received last year were junk mail.
