Chapter 4      Quarantines
Working with Messages in System Quarantines
The message filter or Virus Outbreak Filters feature rule that caused the message 
to be quarantined is placed in the parenthesis. A separate log entry is generated 
for each quarantine in which the message is placed.
AsyncOS also individually logs messages that are removed from quarantine:
Info: MID 483 released from quarantine "Policy" (queue full) 
Info: MID 484 deleted from quarantine "Anti-Virus" (expired)
 
The system individually logs messages after they are removed from all 
quarantines and either permanently deleted or scheduled for delivery, e.g.
Info: MID 483 released from all quarantines 
Info: MID 484 deleted from all quarantines 
When a message is re-injected, the system creates a new Message object with a 
new MID. This is logged using an existing log message with a new MID “byline”, 
e.g.
Info: MID 483 rewritten to 513 by System Quarantine
The Virus Outbreak Filters Feature and the Outbreak Quarantine
The Outbreak quarantine is present when a valid Virus Outbreak Filters feature 
license key has been entered. The Virus Outbreak Filters feature sends messages 
to the Outbreak quarantine, depending on the threshold set. For more information, 
see the “Virus Outbreak Filters” chapter in the Cisco IronPort AsyncOS for Email 
Configuration Guide
.
If the license for the Virus Outbreak Filters feature expires, you will be unable to 
add more messages to the Outbreak quarantine. Once the messages currently in 
the quarantine have expired and the Outbreak quarantine becomes empty, it is no 
longer shown in the Quarantines listing in the GUI.
The Outbreak quarantine functions just like other quarantines — you can search 
for messages, release or delete messages, etc. Messages placed in the Outbreak 
quarantine are automatically released if newly published rules deem the 
quarantined message no longer a threat.
The Outbreak quarantine has some additional features, not available in other 
quarantines: the Manage by Rule Summary link, the Send to IronPort feature 
when viewing message details, and the option to sort messages in sort results by 
Scheduled Exit time.
