The Cisco IronPort Spam Quarantine provides a safeguard mechanism for
organizations that are concerned about “false positives” — that is, legitimate
email messages that are quarantined or deleted as spam. With the Cisco IronPort
Spam Quarantine, you can allow end users and administrators to review messages
that are flagged as spam before making a final determination. In addition, if you
enable the safelist/blocklist feature, end users can exercise control over the
messages that are marked as spam.

Note
You can implement end user access to the Cisco IronPort Spam Quarantine only
for specified users or groups of users. Also, after you initially implement end user
access, you might later decide to disable access if end users rarely view and
release messages in the quarantine.

You can configure AsyncOS to send a notification email to end users, informing
them of quarantined spam and suspected spam messages. The notification
contains a summary of the messages currently in the Cisco IronPort Spam
Quarantine for that user. The user can view the messages and decide whether to
have them delivered to the Email Inbox or delete them. Users can also search
through their quarantined messages. Users can access the quarantine through the
notification message, or they can access the quarantine directly by using a web
browser. (Direct end user access to the quarantine requires authentication. For

All administrator-level users (such as the default admin user) can access and
modify the Cisco IronPort Spam Quarantine. AsyncOS operator users can view
and manage the quarantine content, but they cannot change the quarantine
settings. Mail end users can access their own messages in the quarantine if you
enable end user access to the Cisco IronPort Spam Quarantine.
