This may be a permanent or a transient condition. Active Directory Lightweight Directory Services will try this operation again later when it sends another replication message according to the schedule of the intersite connection. 
 
User Action 
-If the SMTP service has given up too quickly, adjust the SMTP retry parameters using the SMTP service manager. 
 
-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.
