A
               route is a specific "To" and "From" combination that includes a recipients' and sender's
               email
               addresses, LDAP users or groups, or address groups. You can also configure exceptions
               to a
               route.
 
            Senders and recipients must be on the Internal Addresses list
               if you select incoming messages or outgoing messages when adding
               a new rule or modifying an existing rule:
            
               - 
                  
If you are configuring an outgoing message, the Internal
                     Address list applies to the senders. 
                
               - 
                  
If you are configuring an incoming message, the Internal
                     Address list applies to the recipients.
                
            
            Use the asterisk wildcard to include a range of email addresses.
               For example:
            
               - 
                  
user@company.com: Adds only the
                     specific address.
                
               - 
                  
*@company.com: Adds any user at the
                     domain company.com.
                
               - 
                  
*@*.company.com: Adds any user at any
                     subdomain of company.com. 
                  For example, user1@accounting.company.com would
                     be included.
                
               - 
                  
*@*: Adds all addresses.
