Cisco AsyncOS 8.0.1 for Email User Guide
 
Chapter 27      Quarantines
  Using Safelists and Blocklists to Control Email Delivery Based on Sender
Enable and configure the Spam Quarantine. Because the safelist and blocklist is accessed from 
the Spam Quarantine, you must enable this feature to use safelists and blocklists. For information, 
see 
.
Enable and configure the Safelist/Blocklist feature. Once the Spam Quarantine is enabled, you 
enable and configure the Safelist/Blocklist feature. You must also configure a blocklist action for 
blocklisted email (quarantine or delete). For information, see 
Backup and restore the Safelist/Blocklist database. When upgrading, you need to backup and 
restore the Safelist/Blocklist database. For information, see 
Synchronize Safelist/Blocklist databases. When end users enter safelist or blocklist entries, the 
settings are saved to a database which is periodically synchronized with a database that is used by 
AsyncOS when processing email. If the Spam Quarantine is maintained on a Security Management 
appliance, the administrator must configure the Safelist/Blocklist database to synchronize with the 
Email Security appliance. For information, see 
.
Troubleshooting Safelists and Blocklists. To troubleshoot safelists and blocklists, you can check 
logs, alerts. For more information, see 
Configuring Safelists and Blocklists 
Before You Begin

blocklists.
Procedure

Select Monitor > Spam Quarantine
Step 2

Step 3
Select Enable Safelist/Blocklist Feature.
Step 4
Select Quarantine or Delete for the Blocklist Action.
Step 5
Specify the Maximum List Items Per User. This value represents the maximum number of addresses or 
domains a user can list in each safe and block list.
Step 6

Backing Up and Restoring the Safelist/Blocklist Database
To save a backup of the safelist/blocklist database, the Cisco appliance saves the database as a .CSV file. 
The .CSV file is maintained separately from the XML configuration file that contains your appliance 
configuration settings. If you upgrade your appliance or run the Installation Wizard, you should back up 
the Safelist/Blocklist database to the .CSV file. 
When you back up a file, the appliance saves a .CSV file to the 
/configuration
 directory using the 
following naming convention:
slbl<timestamp><serial number>.csv
