Policy References

Policy references are items that can be referenced when you define your security policy. For example, you can add one of the references, Informs, to your policy route to send notifications when specific content rule conditions are met.

Peer Gateways

When you peer Secure Email Gateway with other types of Gateways, you will see features in one that are only supported in the other. For more information, see Peer Gateways.

Lexical Expression Lists

Collections of words or phrases (lexical expressions) with associated weightings. See Lexical Expressions for more information.
Informs

Email messages that can be sent as a notification, for example to the original message sender or the system administrator. See Informs for more information.
Filename Lists

Lists of one or more file identification masks for identifying the presence of particular files or file types in a communication. See Filename Lists for more information.
Custom Media Types

Lists of one or more hexadecimal signatures that can be identified at the start or end of a media type file. The Gateway provides a number of custom media types and you can also create your own. See Custom Media Types for more information.
URL Lists

Lists of specific URLs used by content rules. URL Lists can be dynamic, updating in real-time to known malicious threats, or customized. You can apply URL Lists to sanitize content when a suspicious URL is encountered by the Gateway. See URL Lists for more information.

Policy References for the mail type products

Address Lists

Lists of email addresses such as a departmental team within your organization or a regional office. See Email Address Lists for more information.
Disposal Actions

The principal action which the Gateway performs on an email message. It determines whether the message is delivered, held, dropped (deleted), non-delivered, or relayed to a server. See What To Do? actions for more information.
ImageLogic

The ImageLogic feature enables you to control the circulation of images via email. ImageLogic processes images contained in messages and will check to see if there is a matching image that has been stored in the image database before analyzing the image for unacceptable features if no matching image has been found. An image will be classified as acceptable or unacceptable depending on this analysis.
Message Annotations

Text items (in both plain text and HTML format) that can be added to an email message. Typically you might create an annotation for use as a commercial disclaimer or to notify a recipient that the Gateway has stripped malicious content from the message. See Message Annotations for more information
Manager Relationships

Lists of manager relationships. See Manager Relationships for more information

In the editing page for each item under Policy References, there is the Usage panel at the top, describing which policy routes or content rules the item is currently applied to. If you click the name of a policy route or a content rule, you will be navigated to the Modify Policy Route page of that route, or the editing page of that rule. If an item is not applied to any policy routes or content rules, a message indicating this is displayed at the top, instead of the Usage panel.
