Table: Content filtering policy conditions message parts describes the parts of a message for which you can create conditions in content filtering policies. It also specifies the message part or resource that Symantec Messaging Gateway uses to evaluate that condition.

See Considerations for content filtering policy conditions.

Condition

What is evaluated

Example

Subject, body, or attachments

HTML tag scanning

Scans content within HTML tags in the message body

An HTML tag consists of all items within the tag brackets.

You can enable the option to scan HTML tags when you select the option to scan the Text in the subject, body or attachments of a message. This option is disabled by default.

Symantec Messaging Gateway always scans HTML body content regardless of whether you enable this option.

For example:

If any part (including HTML tags) of the message contains five or more words in dictionary "EAR CCL Keywords."

Attachment content

Text within an attachment file

Finds all attachments that contain the word "discount" more than three times

Body

Contents of the message body

This component test requires more resources to process. So you may want to add it as the last condition in a filter to optimize the filter.

When you select the option to scan a body part of a message, you can also enable the option to scan HTML tags. An HTML tag consists of all items within the tag brackets. This option is disabled by default.

Symantec Messaging Gateway always scans HTML body content regardless of whether you enable this option.
