    Check the connection from the SAP system to node SMTP. Perhaps the node is not assigned to the correct destination. If so, correct this in Customizing. In production operation, it is advisable to reroute provisionally to another node. You should therefore notify your system administrator.

    XS816 error are likely caused by a problem with the connection between the SAP system and mail server.

    It may happens due to the following, ( try to check port is open or not )

    1. Check SMICM that ICM is running or not.

    2. Check configuration with the help of note SAP Note 421359.

    3. Check whether SMTP service/port are active and are correct.

    4. Check these SAP Note 757804, 634006, 455140.
