Kaspersky Anti-Spam is a software suite filtering e-mail in order to protect mail system users from unsolicited mass mail (spam).
Kaspersky Anti-Spam filters incoming mail when received by SMTP-protocol, i.e. before the messages get into inbox. Kaspersky Anti-Spam uses administrator-defined rules to Process received messages accordingly. Namely, it delivers a message without modifications, blocks it, generates a notification informing that a message could not be received, adds or modifies message header and performs other actions specified by the administrator.
The application uses a new intellectual technology Spamtest to recognize unwanted mail. The technology includes integrated methods to recognize spam: a DNS-based real time Black Hole list (DNSBL), a check based on SPF and SURBL, analysis of the formal message parameters, linguistic heuristics, signatures updated in real-time and graphic spam recognition.
