Kaspersky?Anti-Spam is a highly intelligent system dedicated to protecting businesses with small and medium-size networks against dreaded spam. Kaspersky?is the result of a joint effort between the specialists of Kaspersky Labs and Ashmanov and Partners.
The solution's effectiveness is provided by the simultaneous use of "black lists" (updated online), message sample comparisons and powerful heuristic analysis (intelligent content analysis) of incoming messages. The software comprehensively filters incoming electronic messages before they reach end-user mailboxes. This enables organizations to significantly decrease mail system maintenance costs, as well as to reduce the amount of valuable time wasted handling spam.
Kaspersky?Anti-Spam can be used as a filter for any mail system - Sendmail, Qmail Postfix, MS Exchange and more. Depending on the operating system a company's mail system is running, Kaspersky?Anti-Spam can be installed on a remote computer or directly on the mail server.
Powerful Message Filtration Capabilities
Several methods are used to prevent the delivery of "unwanted" messages to mailboxes. Employed are techniques based on filtering message attributes such as: sender and recipient addresses, message size, addresses used for message redirection and message header. Address filtration checks for e-mail and IP addresses in the "black lists" and special RBL* database, which contains the IP-addresses of mail servers conducting uncontrolled mail distribution.
* - Such mail servers receive messages from any address and then redirect them to any existing address. When spam messages are distributed from a particular address and no preventive actions are taken by server administrators, this server's address can be added to the RBL
