Understanding email filtering
Symantec Mail Security for SMTP provides a wide variety of actions for filtering
email, and allows you to either set identical options for all users, or specify
different actions for distinct users or groups.
You can specify groups of users based on email addresses, domain names, or
LDAP groups. For each group, you can specify an action or group of actions to
perform, given a particular verdict.
