According to a report on spam trends in September by Commtouch Software, which sells proprietary anti-spam products, China heads the list of spam hosting countries, although the U.S., U.K., Brazil and Romania lead the world in sending phishing and fraudulent e-mails.

Commtouch detected in September that facilities in China reclaimed the dubious distinction of hosting the majority of Web sites referenced in spam e-mail (67.01 percent), an increase from the previous month in which hosting facilities in South Korea, at 47 percent, held the top spot on this list.
