-If the destination domain controller is unknown or not directly connected to the local domain controller, it may be necessary to configure  SMTP to use a gateway to route the mail to the target system. You can do this using the SMTP service manager.  
  
-If the DNS address for the destination domain controller cannot be resolved, or if network connectivity cannot be established, consult your network administrator.  
  
-If the mail message is too large, either increase the message size limit of the SMTP service or disable limit checking.
