Spam Quarantine thresholds let you control the maximum size for Spam Quarantine. You can use the Expunger to enforce Spam Quarantine threshold settings. Only the administrators that have Full Administration rights or Manage Settings modify rights can modify quarantine settings.
Since the Expunger maintains the maximum size of Spam Quarantine, the quarantine can exceed maximum thresholds until the Expunger runs at the next scheduled interval.
Before you modify the Spam Quarantine thresholds, ensure that you understand the implications and considerations.
Table: Spam Quarantine Thresholds describes the Spam Quarantine thresholds that you can configure.
