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.

For Active Directory servers, the default query string 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
