In the console on the primary navigation bar, click Policies.
In the sidebar under Antispam, click Premium AntiSpam Settings.
In the content area, under Symantec Premium AntiSpam Settings, check Enable Symantec Premium AntiSpam.

To bypass AntiSpam filtering of email messages from verified senders check Fast Pass.
Under DNS IP reputation, check the Enable DNS IP Reputation option. This DNS-based IP (DNS IP) reputation allows the delivery of the Symantec Global Bad Senders list, which is the largest Symantec IP reputation list.
Note: | It is highly recommended to use either Enable Ruleset based sender IP or DNS IP reputation services to avoid heavy network bandwidth consumption. |
