Cisco IronPort’s Outbreak Filters feature includes special filters that act 
proactively to provide a critical first layer of defense against new outbreaks. 
Based on Outbreak Rules published by Cisco IronPort, messages with 
attachments of specific filetypes can be sent to a quarantine named Outbreak.

Messages in the Outbreak quarantine are processed like any other message in a 
quarantine. For more information about quarantines and the Work Queue, see

Cisco IronPort AsyncOS allows you to filter incoming or outgoing messages and 
place them into quarantines. Quarantines are special queues or repositories used 
to hold and process messages. Messages in quarantines can be delivered or 
deleted, based on how you configure the quarantine.

The following Work Queue features can send messages to quarantines:

Message Filters

Anti-Virus

Outbreak Filters

Content Filters

Messages released from quarantines are re-scanned for viruses.

See the “Quarantines” chapter of the Cisco IronPort AsyncOS for Email Daily
