Spam filtering is automatically enabled company-wide through the default anti-spam policies (connection filter, spam filter, and outbound spam). As an administrator, you can view and edit, but not delete, the default anti-spam policies so that they are tailored to best meet the needs of your organization. For greater granularity, you can also create custom policies and apply them to specified users, groups, or domains in your organization. By default, custom policies take precedence over the default policy, but you can change the priority of your policies.
