RSA Enterprise Manager and Language Support
The Email Security appliance displays any data it receives from RSA Enterprise Manager in the language 
that was used in Enterprise Manager. The appliance does not display this information in the language 
you selected for the appliance interface. This applies to DLP policies, content matching classifiers, 
dictionaries, and anything else created in Enterprise Manager that the appliance receives in the data 
package. For example, if the DLP policies and classifiers from Enterprise Manager were written in 
English but the interface of the Email Security appliance is displayed in French, the Email Security 
appliance displays the name and descriptions of the DLP policies and classifiers from Enterprise 
Manager in English. The rest of the interface remains in French.
Using Enterprise Manager with Clustered Appliances
If you are using Enterprise Manager to manage the DLP policies for clustered Email Security appliances, 
be aware of the following:
The Email Security appliance sends Enterprise Manager the outgoing mail policies and message 
actions from the lowest cluster level where these settings are configured. If these settings are 
configured differently at the cluster and machine level, the Email Security appliance sends 
Enterprise Manager the settings from the machine level. If you want to use the outgoing mail 
policies and message actions configured at a higher cluster level, delete the policies and actions 
defined at the lower levels that you do not want to use.
The Email Security appliance uses the Data Loss Prevention mode specified at the lowest cluster 
level where this setting is configured. For example, if a clustered appliance is configured to use the 
local RSA Email DLP mode at machine level and RSA Enterprise Manager at the cluster level, the 
appliance uses RSA Email DLP for data loss prevention and does not communicate with Enterprise 
Manager.
About Deleting and Disabling Policies in Enterprise Manager Deployments 
Deleting and Disabling DLP Policies 
To delete DLP policies, use Enterprise Manager. 
To disable or enable DLP policies, use the Email Security appliance. Go to Mail Policies > DLP 
Policy Manager
Any outgoing mail policies associated with the disabled DLP policy will skip the policy when 
evaluating messages for DLP violations.
Deleting Outgoing Mail Policies 
If you try to delete an outgoing mail policy that is linked to a DLP policy, the Email Security appliance 
displays a message warning you that the mail policy is currently in use. If you delete the policy anyway, 
Enterprise Manager automatically unlinks the deleted outgoing mail policy from any DLP policy that 
used it. Other than not scanning for messages based on the configuration of the deleted mail policy, DLP 
scanning continues to work as before. The next DLP policy package sent to the Email Security appliance 
by Enterprise Manager will not include anything related to the deleted mail policy.
