Spam Quarantine Alias Consolidation Queries
If you use spam notifications, the spam quarantine alias consolidation query consolidates the email aliases so that recipients do not receive quarantine notices for each alias. For example, a recipient might receive mail for the following email addresses: john@example.com, jsmith@example.com, and john.smith@example.com. When you use alias consolidation, the recipient receives a single spam notification at a chosen primary email address for messages sent to all of the user’s aliases.
To consolidate messages to a primary email address, create a query to search for a recipient’s alternate email aliases, and then enter the attribute for the recipient’s primary email address in the Email Attribute field.
For Active Directory servers, the default query string (which may or may not be different for your deployment) is (|(proxyAddresses={a})(proxyAddresses=smtp:{a})) and the default email attribute is mail . For OpenLDAP servers, the default query string is (mail={a}) and the default email attribute is mail . You can define your own query and email attributes, including multiple attributes separated by commas. If you enter more than one email attribute, Cisco recommends entering a unique attribute that uses a single value, such as mail , as the first email attribute instead of an attribute with multiple values that can change, such as proxyAddresses .
To create the query in the CLI, use the isqalias subcommand of the ldapconfig command.
