McAfee® SpamKiller® for Mail Servers
McAfee® SpamKiller® for Mail Servers provides unmatched spam protection and performance for Microsoft® Exchange and Lotus® Domino™ mail servers, with an out-of-box detection rate of up to 95%, and a minimal false positive rate under 0.5%. By keeping your network free of spam, McAfee SpamKiller ensures high user productivity, enforces HR policies against inappropriate content, conserves network bandwidth, and keeps spam-related security risks to a minimum. Key Benefits
  • Instant, proactive spam detection – Spam is stopped cold through advanced, rules-based scanning and scoring plus five levels of intelligent spam detection

  • Personalized detection rules – Administrators can easily modify the default rules, and users can create their own black- and whitelists to control what they do and don’t want to receive

  • Multiple quarantine options – Detected spam can be selectively routed depending on its spam probability “score”; this reduces false positives by allowing users to check low-rated messages

  • Centralized management, monitoring, and detailed reporting – SpamKiller is fully integrated with McAfee ePolicy Orchestrator®, the industry’s leading tool for enterprise-class system security management

  • Integrated anti-virus protection – SpamKiller may be augmented with McAfee GroupShield® for complete, comprehensive anti-virus security and content filtering

Product Features

Highly accurate rules-based scanning
The SpamKiller product family is powered by the McAfee SpamAssassin® engine, which scores or rates emails based on a series of tests. This highly effective technology catches up to 95% of all spam email, with a very low false-positive rate of less than 0.5%.


Spam scoring system
Spam scoring is an essential spam-detection safeguard, as it can differentiate legitimate “gray-area” messages that less sophisticated products would incorrectly label as spam. Utilizing an extensive rule set, the McAfee SpamAssassin scoring system runs literally hundreds of rules against each email. Rules have a negative or positive score, with negative denoting legitimate email and positive indicating unsolicited email or spam. The total score is the email’s “overall spam rating.”

Five levels of protection
  • Integrity analysis – SpamKiller examines the header, layout, and organization of each email message, to identify the common characteristics of spam
  • Heuristic detection – A series of internal tests determines the likelihood of a message being spam; each test carries a score to help reduce false positives
  • Content filtering – Each email is checked for key words or phrases that might indicate that the message is spam
  • Black- and whitelists – Blacklists are made up of known spam senders, who are blocked; whitelists are made up of approved senders, whose email is allowed in. Users can create their own lists to control which messages reach their inbox
  • Self-tuning – SpamKiller learns the characteristics of the email users receive and adjusts the "overall spam rating" accordingly, reducing the chance of false positive identification


Advanced content management (Microsoft Exchange only)

Capabilities include group-based policy with granular departmental rule sets; lexical scanning of emails and attachment content based on content management rules; content scanning of over 300 email attachment types, including Adobe® Acrobat and Microsoft Office; true file-attachment-type identification to prevent common rule evasion; automatic alerting when an email or attachment contains sensitive or offensive information; the ability to replace any email or attached document containing words or phrases specified in content rules; prevention of sensitive corporate data from leaving the organization.

Tiered spam routing

Detected spam can be routed selectively, depending on its score. An email with a score below 5 could go to the user’s inbox; messages scored 5 through 14 could go to the user’s junk folder, and email rated 15 or higher could go to the system junk folder. This helps reduce false-positives by allowing users to personally check low-rate or “gray-area” messages.

Centralized Management and Detailed Reporting

McAfee SpamKiller is fully integrated with McAfee ePolicy Orchestrator for comprehensive policy management and detailed graphical reporting. Administrators can configure and enforce policy and monitor the effectiveness of their security and anti-virus safeguards. Policies can be configured for anti-virus and content filtering rules for individuals or groups of users.
