Policy groups collect the spam, malware, and content filtering policies for a set of users.
When SMG processes a message, the results for each sender or recipient can differ, based on policy group membership. For an inbound message, SMG processes the message for each recipient according to the filtering policies in the recipient's policy group. For an outbound message, it is the sender's policy group that determines processing.
By default, Symantec Messaging Gateway assigns the default filter policies for spam, malware, and threat defense to the policy groups that you create. Content filtering does not have default policies, so no content filtering policies are assigned to new policy groups. After you create your own filter policies, you can edit your policy groups to assign the new policies.
When a recipient or sender is a member of more than one policy group, only the group with the highest group precedence applies. The higher the group appears in the list on the Policy Groups, the higher the group's precedence.
The Default policy group is always the last group in the list. You cannot change the precedence of the Default policy group.
If you enabled probe participation, the Probe Account policy group appears in the list of policy groups. If only this list does not have pre-existing custom policy groups, then Probe Account policy group is the first group in the list. You can change the precedence of the Probe Account policy group. When you choose to edit the Probe Account policy group, the Probe Accounts page appears.
The policy group management options let you do the following:
Set policy group precedence, which determines the filter policies applied to each message.
Edit policy group membership and actions.
Enable and disable policy groups.
Delete policy groups.
