Incoming Mail Policies Page: Defaults for a Brand New Appliance

Note

In this example, the Incoming Mail Policy will use the default anti-spam settings for when the Spam
Quarantine is enabled.

Enabled, Disabled, and “Not Available”

The columns in a mail policy table (either incoming or outgoing) display links for the state of the security
service for each policy name. If a service is enabled, the word “Enabled” or a summary of the
configuration is displayed. Similarly, the word “Disabled” is displayed if a service is disabled.

“Not Available” is displayed as a link if the license agreement for a service has not been accepted yet or
a service has expired. In these cases, clicking the “Not Available” link will display the global page within
the Security Services tab, rather than the page where you can configure per-policy settings for a service.
An alert is displayed to let you know that your page has changed to a different tab. See
