Step 1 Select the entry or entries by marking the corresponding checkbox in the left column.
Step 2 Click Delete.
Step 3 Confirm the deletion.
Note that you cannot delete the default Destination Control entry.
Importing and Exporting Destination Control Configurations
If you are managing multiple domains, you can create a single configuration file to define Destination
Control entries for all of the domains and import it onto the appliance. The format of the configuration
file is similar to a Windows INI configuration file. The parameters for a domain are grouped in a section
with the domain name as the section name. For example, use the section name [example.com] to group
the parameters for the domain example.com. Any parameter that is not defined will be inherited from
the default Destination Control entry. You can define the parameters for the default Destination Control
entry by including a [DEFAULT] section in the configuration file.
Importing the configuration file overwrites all of appliance’s Destination Control entries, except for the
default entry unless the configuration file includes the [DEFAULT] section. All other existing Destination
Control entries will be deleted.
You can define any of the following parameters for a domain in the configuration file. All parameters are
required for the [DEFAULT] section except for the bounce_profile parameter:
Table 2-9 Destination Control Configuration File Parameters
Parameter Name Description
ip_sort_pref Specifies the Internet Protocol version for the domain.
Enter one of the following values:
PREFER_V6 for “IPv6 Preferred”
REQUIRE_v6 for “IPv6 Required”
PREFER_V4 for “IPv4 Preferred”
REQUIRE_v4 for “IPv4 Required”
max_host_concurrency The maximum number of outbound connections that will
be made by the Cisco IronPort appliance to a given host.
If you define this parameter for a domain, the limit_type
and limit_apply parameters must also be defined.
max_messages_per_connection The maximum number of messages allowed for a single
outbound connection from the Cisco IronPort appliance to
a given host before initiating a new connection.
recipient_minutes The period of time — between 1 and 60 minutes — that the
Cisco IronPort appliance will count the number of
recipients. Leave undefined if no recipient limit should be
applied.
