Cisco Cisco Email Security Appliance C390 사용자 가이드

Similarly, if you create a mailflow policy that skips anti-spam scanning for certain 
message recipients, these recipients will not have their safelist and blocklist 
settings applied. 

To use safelists and blocklists, the administrator must complete the following 
tasks:

Enable and configure the Ironport Spam Quarantine. Because the safelist 
and blocklist is accessed from the IronPort Spam Quarantine, you must 
enable this feature to use safelists and blocklists. For information, see 

.

Enable and configure the Safelist/Blocklist feature. Once the IronPort 
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 IronPort Spam Quarantine is maintained on an M-Series 
appliance, the administrator must configure the Safelist/Blocklist database to 
synchronize with the C-Series appliance. For information, see 

Troubleshooting Safelists and Blocklists. To troubleshoot safelists and 
blocklists, you can check logs, alerts. For more information, see 

You can enable and configure settings for safelists and blocklists from the 
Quarantines page.
