About Content Filtering

The content filter evaluates inbound and outbound messages on the basis of user-defined policies. Each policy contains a list of keywords and phrases. Content filtering evaluates the header and/or content of messages by comparing the messages with the list of keywords. When ScanMail finds a word that matches a keyword it can take action to prevent the undesirable content from being delivered to Exchange clients. ScanMail can send notifications whenever it takes an action against undesirable content.

ScanMail applies the content filtering policies to email messages according to the order shown in the Content Filtering screen. You can configure the order in which the policies are applied. ScanMail filters all email messages according to each policy until a content violation triggers an action that prevents further scanning (such as "delete", or "quarantine"). You can change the order of these policies to optimize content filtering.

The content filter provides a means for the administrator to evaluate and control the delivery of email messages on the basis of the message text itself. It can be used to monitor inbound and outbound messages to check for the existence of offensive or otherwise objectionable message content. The content filter also provides a synonym checking feature, which allows you to extend the reach of your policies.
