Synchronizing Safelist and Blocklist Settings and Databases
With the Security Management appliance, you can easily synchronize the safelist/blocklist databases on 
all managed appliances. 
Note
Before you can synchronize safelist/blocklist databases, you need to enable the safelist/blocklist feature 
and add at least one managed appliance to the Security Management appliance. For more information 
about adding managed appliances, see 
To synchronize safelist/blocklist databases, click the Synchronize All Appliances button on the 
Management Appliance > Centralized Services > Spam Quarantine page.
If you use the centralized management feature to configure multiple appliances, you can configure 
administrator settings using centralized management. If you do not use centralized management, you can 
manually verify that settings are consistent across machines.
For more information about using FTP to access appliances, see Appendix A, `IP Interfaces and 
Accessing the Appliance,' on page 1.
Message Delivery for Safelists and Blocklists
When you enable safelists and blocklists, the Email Security appliance scans the messages against the 
safelist/blocklist database immediately before anti-spam scanning. If the appliance detects a sender or 
domain that matches an end user’s safelist/blocklist setting, the message is splintered if it has multiple 
recipients with different safelist/blocklist settings. For example, sender X sends a message to both 
recipient A and recipient B. Recipient A has safelisted sender X, but recipient B has no entry for the 
sender in either the safelist or the blocklist. In this case, the message may be split into two messages with 
two message IDs. The message sent to recipient A is marked as safelisted with an X-SLBL-Result-Safelist 
header, and it skips anti-spam scanning. The message bound for recipient B is scanned with the 
anti-spam scanning engine. Both messages then continue along the pipeline (through anti-virus 
scanning, content policies, and so forth), and they are subject to any configured settings. 
If a message sender or domain is blocklisted, the delivery behavior depends on the blocklist action 
settings. Similar to safelist delivery, the message is splintered if there are different recipients with 
different safelist/blocklist settings. The blocklisted message splinter is then quarantined or dropped, 
depending on the blocklist action settings. 
Note
You specify blocklist actions in the external spam quarantine settings on the Email Security appliance. 
For more information, see 
.
If you configure the blocklist action to quarantine messages, the message is scanned and eventually 
quarantined. If you configure the blocklist action to delete messages, the message is deleted immediately 
after safelist/blocklist scanning.
