aspelling writes " We all know that majority of consumer electronics and other goods sold in US stores is produced in China. But China specialty extends beyond consumer electronics, clothes and automotive components. According to Commtouch Software research 71% of all spam servers are located in this People Republic. "Since Jan. 1, we've seen probably a 30% to 40% increase" in spam traffic" Commtouch CEO says. BusinessWeek reports about this issue."

    The direct link want your e-mail address (*shudder*)
    Go to the press release (it is listed on the page) and click on the link for the white paper

    But surprise, surprise, the "best solution" is the one they sell, but it's still an interesting read.

      Question: How does "71% percent of spam servers are located in China" quoted in the article correlate with the whitepaper stating "Figure 1: North America and International Spam Messages Sent Daily" depicting 2005: North America 8.5 billion, International 11 billion?

      Maybe it is in the subtle difference of spam messages sent, and servers used to send them.

    there was a tip posted to NANOG this morning. you can use china.blackholes.us as a RBL (look at their page, they have other lists) to effectively block all mail from china's IPs

    Just for other people's info... since I didn't know:
    Tarpitting discourages spamming without permanently blocking an offending IP address. Tarpitting works by monitoring traffic and applying sluggish responses to remote IPs showing spam-like behavior. For example, if an IP sends too many messages to users during an email session, tarpitting starts slowing MDaemon's response. If the spam-like behavior includes excessive unknown addresses during a session, the remote server can be suspended from access for a user-specified amount of time.

    That's not going to help too much. According to the article, 71% of the URLs appearing in spam messages point to websites hosted in China however 60% of spam messages are sent from the US. In fact, China (although second) is only the location of the mail servers sending about 6% of the spam messages that they analyzed. The post was not too clear on that but the source article is.

    Doesn't anyone read the article?

    It said that 71% of the URLs in spam go to web servers in China, not that 71% of spam comes from China!

    The vast majority of spam that hits my mail server comes from the US (comcast, rr.com, etc) machines that have been compromised.

    Tools like bigevil.cf (SpamAssassin plugin) help me to filter those spams with Chinese URLs.
