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.
You can, for example, create policies to check for:
