In a policy, you can configure address groups to include a list of email addresses to which Deep Discovery Email Inspector applies the policy. Address groups allow you to organize multiple email addresses into a single group and apply the same policy to every address in the group.
You can create an address group during policy configuration by adding email addresses individually or importing them from a text file.
To use the same address group on multiple Deep Discovery Email Inspector appliances, you can export an address group from the source Deep Discovery Email Inspector appliance and import the text file on a target Deep Discovery Email Inspector appliance.
