Following 21cn.com's recent implementation of Hanqi's Knowledge-based Anti-spam Gateway and weeks after global anti-spam group Spamhaus lifted a worldwide ban on Tom.com's (TOMO) email servers, Tom.com has now introduced KBAS into its free email service to filter outbound spam.

Outbound spam refers to large numbers of unwanted email sent via SMTP by a server of an email service provider. This kind of spam icauses serious impairments which include causing the IP address of the email server to be listed in a realtime blackhole list of a global service like Spamhaus; causing a lot of email to be returned, hindering the normal email communications of a provider; occupying bandwidth and causing a waste of communication resources; and jeopardizing the email service provider's reputation.

As traditional spam filtering technology mainly targets incoming spam and ignores the outbound spam, it can not help control the spam spreading from the root. At present, the more mature anti-spam products widely adopted by the international community usually use hardware equipment which features such advantages as simple structure, easy installation and good compatibility, but these products have some obvious defects, including difficulty in upgrading hardware and high costs. With the increase of both the email users and spam, more new hardware is needed, or the efficiency and performance of the anti-spam products will be decreased. A better solution under this circumstance is the use of an application software.

The KBAS system developed by Shenzhen-based Hanqi Technology is reportedly a better anti-spam software solution than many hardware-based systems. The system is suitable for various operation systems and hardware environment, and it is reliable and efficient. In particular, it makes a great breakthrough in filtering Chinese-language spam.

One of the main reasons for Tom.com to choose KBAS is reportedly because of its powerful filtering function. When KBAS is installed separately in a dozen outbound UNIX servers, the email sent out will be first filtered by KBAS and only non-spam emails will ultimately be sent out. Statistics show that the daily emails sent before and after KBAS is installed is more than 50 million and several million, respectively. This means that KBAS will filter more than 40 million spam each day on high performace systems like those used by Tom.com.

Currently, nearly all the portal email service providers in China face the problem of controlling unsolicited bulk email sent out from their systems. Anti-spam groups like Spamhaus have long had problems with many Internet service providers and portals in China who do not take proactive measures to limit the amount of unwanted emails leaving their own servers. Hanqi Technology's KBAS software system is specially designed for these email service providers.

  1. I am have great difficulty getting my email reply messages to college recruitment agents located in China. Their messages are coming through fine from China, but my reply messages are being blocked by provider servers there in China. How can I get the China servers to allow my email to go through???

  2. Ron, you are not the only one with the problem. I have suppliers in China whose e-mails come through but mine to them get returned. I am getting extremely frustrated.

  3. I have some important email to send to one friend and it is blocked. I have no other way of getting the message to her. I hate spam, mostly because of inept filtering like this. I encourage all my students to get email service from a "not Chinese company" for business communication. I had the same problems with sina . Yahoo and Hotmail block without these problems. Seems China is again ready to isolate itself from the rest of the world.
