Kaspersky Antispam Enterprise
vendor: Kaspersky Labs

Kaspersky® Anti-Spam protects both users of company mail systems and Internet providers from unsolicited mass mailing or spam.

Kaspersky Anti-Spam helps mail system users eliminate unwanted mail. It employs intelligent spam detection technology, which was developed using Kaspersky Lab’s extensive experience in protecting large-scale mail systems.

Features

Protection from spam

• Lists. Messages are checked against blacklists of email addresses and sender IP addresses (e.g., DNSBL or DNS-based Blackhole Lists), which are maintained by service providers and public organizations. Administrators can also compile their own whitelists (e.g., friends list) of users, whose messages will automatically be delivered without undergoing analysis.

• Analysis of formal attributes. Attributes that are typical of spam messages include modifications of sender addresses, no recipients specified or an excessive number of recipients, and the absence of an IP address in the DNS system. The size and format of messages are also taken into consideration during analysis.

• Linguistic heuristic analysis. Both messages and attachments are filtered according to their content, which is scanned for specific word combinations and their distribution within messages.

• Signature analysis. When a new spam message is detected, it can be automatically assigned a lexical signature, which is added to the signature database. From this signature, Kaspersky Anti-Spam can recognize the message or modified versions of the message.

• Detection of graphic spam. Graphic signatures are created and added to the signature database in the same way as for ordinary spam. Using graphic spam analysis, images rather than words are analyzed in messages that include both images and text.

Administration

• Flexible settings. System administrators can adjust the stringency level of filtration, maintain sender blacklists and whitelists, enable or disable individual filtration rules and set the application to block mail encoded for East-Asian languages.

• Configurable processing rules. The processing rules for spam can be configured to best suit the needs of each individual user. The application can automatically delete each spam message, send notification of refusal to the sender or redirect a message (or copy of the message) to the quarantine folder. Administrators can also add a marker to the letter’s subject line or headers, so that the message can be sent to the recipient and filtered at the level of the mail client.

• Updates to databases. Administrators have the option of setting their own schedule for receiving updates (by default, updates are downloaded every 20 minutes).
