About configuring the user and distribution list notification digests
By default, a notification process runs at 4 A.M. every day. The process determines if users have new spam messages in Spam Quarantine since the last time the notification process ran. If so, it sends a message to users who have new spam to remind them to check their spam messages in Spam Quarantine. The process can also send notification digests to users on distribution lists.
Notification messages and notification settings are disabled if LDAP is not configured or if administrator-only access is enabled.
By default, the notification templates for standard quarantined messages and quarantined distribution list messages are different. Separate templates let you customize the notification templates for each type of quarantined message.
