Local Versus External Spam Quarantine

A local spam quarantine stores spam and suspect spam on the appliance . An external spam quarantine can store these messages on a separate Cisco Content Security Management appliance .

Consider using an external spam quarantine if:

• You want a centralized location to store and manage spam from multiple appliances .
• You want to store more spam than the appliance can hold.
• You want to regularly back up the spam quarantine and its messages.
