Synchronizing Safelist and Blocklist Settings and Databases
When an end user creates a safelist or blocklist, the setting is saved to a database. If the Spam Quarantine
exists on a Security Management appliance, this database must be synchronized with a database on the
C-Series appliance before the safelist/blocklist settings are applied to incoming mail. When the Spam
Quarantine exists on a C-Series appliance, the database must be synchronized with a read-only database
that is used when processing the mail queue. The amount of time it takes to automatically synchronize
these databases depends on the model of the appliance. The following table shows the default settings
for updating safelists and blocklists:
