The
               first step in adding a rule is configuring the following:
 
            
               - Route
 
               -  A specific "To" and "From" combination that includes a recipient's and sender's
                  email addresses, LDAP users or groups, or address groups. You can also configure
                  exceptions to a route.
 
            
            
               - Route type
 
               - The direction of SMTP traffic, POP3 traffic, or all traffic.
