Modifying a Machine List

References to Email policy content are only available when an Email Gateway is included in the peer group.

You can modify a Machine List to change the machines that it defines.

To modify a Machine List

From the Policy References section of the Policy Center Home page, click Machines. The Manage Machine Lists page appears, listing any existing Machine Lists.

Select the Machine List to modify and click Edit. The Modify Machine List page appears, displaying the details of the Machine List.
The Overview area enables you to provide a name and optional notes for the Machine List. To edit the Overview information:

Move the mouse pointer over the Overview area and click Click here to change these settings.
Edit the Name if required. The Gateway provides a default name. Change this to something more meaningful, if required.
Edit the Notes if required. You can insert, change, or delete text in this field, which is empty by default.
Click Save.

To add addresses to the list:

Move the mouse pointer over the Machine Addresses area and click New. The New dialog appears in the task panel.
In Machine Address, type a machine's IP address, which must be in the format: nnn.nnn.nnn.nnn. You can construct an address mask using the asterisk wildcard character to specify a range of addresses. For example, 10.44.21.* or 10.44.*.

A machine can also be defined by a fully qualified domain name. You can construct an address mask using the asterisk wildcard character in the initial portion of the domain to specify ranges of hostnames. For example, *.clearswift.com will block all machines in the clearswift.com domain. This functionality is only available when Enabling and Disabling Reverse DNS Lookup is correctly configured and enabled.

Click the Add button below the Address. (The Add button is not selectable unless you have entered an address in the correct format.)
The addresses you defined are listed in the Addresses panel.

To edit or remove an address:

Move the mouse pointer over the Addresses area and select the address to edit.
Select Edit or Delete, as required.

When you have finished modifying your content security policy you must apply the configuration for any changes to take effect. If the Gateways are configured as a group, any group changes should be applied to each Gateway.
