Quarantines
Quarantines are special queues or repositories used to hold and process messages. 
Cisco IronPort AsyncOS allows you to place incoming or outgoing messages into 
one of the appliance’s quarantines: ‘system’ and ‘IronPort Spam.’
Messages in quarantines can be delivered or deleted. You can create, modify, and 
delete quarantines. You can associate users with quarantines. You can view the 
contents of each of your quarantines, search a quarantine for specific messages, 
and send copies of the messages.

Quarantines Overview
As messages are processed by the Cisco IronPort appliance, various actions are 
applied. Filters are applied to messages, messages are scanned for spam or 
viruses, and the Outbreak Filters feature scans messages for targeted attacks. Any 
of these actions can cause a message to be quarantined, depending on your 
settings.
