Although Symantec Messaging Gateway provides default settings for dealing with spam and viruses, you can configure the actions taken on filtered messages to meet your organizational requirements. Content filtering policies offer further methods of managing mail flow into and out of your organization. You can also use content filtering policies to monitor and enforce compliance with regulatory and organizational requirements.
Symantec Messaging Gateway provides a variety of actions for filtering email and allows you to set identical options for all users, or specify different actions for distinct policy groups.
You can assign members to a policy group based on email addresses, domain names, or LDAP groups. For each policy group, you can specify an action or group of actions to perform when a message results in a particular verdict. You specify actions when you create or edit a spam, malware, or content filtering policy. Each of these policies is a filtering policy. For Symantec Messaging Gateway to filter a policy, the policy must be assigned to at least one policy group and it must be enabled.
Verdicts are the conclusions reached on a message by the filtering process. When you create or edit a filtering policy, you specify the conditions that you are looking for in messages. Each condition or set of conditions corresponds to a type of verdict that Symantec Messaging Gateway can assign to a message.
Symantec Messaging Gateway performs actions on an email based on the verdict applied to the message and the policy groups that include the message recipient or sender as a member, as follows:
For inbound email filtering, the policy groups that impact message filtering are those policy groups that include the message recipient.
For outbound email filtering, the policy groups that impact message filtering are those policy groups that include the message sender.
