Working with Messages in System Quarantines
The message filter or 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.
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.

The Outbreak Filters Feature and the Outbreak Quarantine
The Outbreak quarantine is present when a valid Outbreak Filters feature license key has been entered.
The Outbreak Filters feature sends messages to the Outbreak quarantine, depending on the threshold set.
For more information, see the “Outbreak Filters” chapter in the Cisco IronPort AsyncOS for Email
Configuration Guide.

If the license for the 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

to sort messages in sort results by Scheduled Exit time.

Manage Rule by Summary Link
Click the Manage by Rule Summary link next to the Outbreak quarantine in the quarantine listing to view
the Manage by Rule Summary page. You can perform message actions (Release, Delete, Delay Exit) on
all of the messages in the quarantine based on which outbreak rule caused the message to be quarantined.
This is ideal for clearing out large amounts of messages from the Outbreak quarantine. For more
information, see the “Outbreak Filters” chapter in the Cisco IronPort AsyncOS for Email Configuration
Guide.
