Websense Antispam

Email Security Manager Help | Email Security Solutions | Version 7.8.x

The antispam scanning function checks email for various characteristics of spam. If hybrid service is enabled and configured as a pre-filter in an Email Security Gateway Anywhere environment, it performs antispam scanning. If hybrid service is not configured or available, Email Security Gateway uses a combination of other tools for effective antispam scanning.

Hybrid service analyzes incoming email and blocks any message that it recognizes as spam. Mail that hybrid service allows into the system for processing includes a header that contains a scanning result score. Email Security uses this score to determine how to handle the message. If that score exceeds a specified spam threshold, Email Security treats the message as spam and handles it according to applicable policy. In this case, Email Security Gateway does not perform its own, separate antispam scanning.

Hybrid service must be configured and running for this option to be displayed. In the Hybrid Service Analysis box, mark the Use email hybrid service analysis with a threshold score for spam of check box to enable hybrid service spam scoring. Select a spam score from the drop-down list (floating point number between 0 and 20; default is 6).

If this check box is not marked (the default) or hybrid service is not enabled, Email Security Gateway performs a complete antispam scan using any or all of the following tools in the Filter Properties Tools list.

Digital Fingerprinting scanning. When enabled, digital fingerprint scanning checks content for any digital fingerprint of known spam.

LexiRules scanning. When enabled, LexiRules scanning analyzes email content for word patterns commonly found in spam.

Heuristics scanning. When enabled, heuristics scanning checks the message header or content for spam characteristics.

Set the heuristics scanning sensitivity level, from lowest to highest (default is Medium).

If you want message size to determine whether antispam scanning is bypassed, mark the Bypass antispam scanning if message size exceeds check box and enter a message size in KB (default is 1024).
