Chapter 30      Spam Quarantine
  Configuring Spam Management Features for End Users
Recipient Email Aliases and Spam Notifications 
Notifications are sent to each Envelope Recipient that has quarantined email, including mailing lists and 
other aliases. Each mailing list receives a single digest. This means that all subscribers to a mailing list 
will receive the notification. Users who belong to multiple email aliases, or who belong to LDAP groups 
receiving email, or who use several email addresses, may receive multiple spam notifications. The 
following table shows example situations in which users may receive multiple notifications. 
 
If you use LDAP authentication, you can prevent some occurrences of multiple notifications. See 
Users who access the spam quarantine by clicking a link in a notification will not see quarantined 
messages for any other aliases that the end-user may have, unless the appliance is using a spam 
quarantine alias consolidation query for email notifications. If the notification was sent to a distribution 
list that is expanded after processing by the appliance, then multiple recipients may have access to the 
same quarantine for that list. 
This means that all subscribers to a mailing list will receive the notification and can log in to the 
quarantine to release or delete messages. In this case, end users visiting the quarantine to view messages 
mentioned in a notification may find that those messages have already been deleted by other users. 
Note
If you do not use LDAP and you do not want your end users to receive multiple email notifications, 
consider disabling notifications and instead allow end users to access the quarantine directly and 
authenticate via LDAP or POP/IMAP. 
Testing Notifications
You can test notifications by configuring a testing mail policy, and having spam quarantined for just a 
single user. Then, configure the spam quarantine notification settings: Select the Enable Spam 
Notification
 checkbox and do not select Enable End-User Quarantine Access. Then only the 
administrator configured in the Deliver Bounced Messages To field is notified of new spam in the 
quarantine.
