Overriding X.400 Properties

By default, each X.400 connector inherits the settings that are configured on the X.400 protocol. You can use the Override tab on the X.400 connector to override the options that are set on the X.400 protocol.

Override tab

The configuration options that are available on the Override tab are as follows:

• The name entered in the Local X.400 Service name box overrides the local X.400 name of the X.400 transport stack. Some X.400 systems do not support certain characters. If your local X.400 name contains characters that are not supported by the remote system to which you are connecting, use this option to connect to the remote X.400 service using a name that it can support.

• The Maximum open retries option sets the maximum number of times that the system tries to open a connection before it sends a non-delivery report (NDR). The default is 144.

• The Maximum transfer retries option sets the maximum number of times that the system tries to transfer a message across an open connection. The default is 2.

• The Open interval (sec) option sets the number of seconds that the system waits after a message transfer fails. The default is 600.

• The Transfer interval (sec) option sets the number of seconds the system waits after a message transfer fails before resending a message across an open connection. The default is 120.

To set additional override values, you use the Additional Values dialog box. To open this dialog box, click the Additional Values button on the Override tab in the X.400 connector's Properties dialog box.

Additional Values dialog box

In the Additional Values dialog box, you can set these options:

• The options under RTS values set the Reliable Transfers Service (RTS) values. RTS values determine message reliability parameters, such as the checkpoints to include in data and the amount of unacknowledged data that can be sent. You can use the options on an X.400 connectors' Override tab to override the default X.400 service attributes, such as RTS values.

• The options under Association parameters determine the number and duration of connections to the remote system. Each X.400 connector uses the association parameters that are configured on the X.400 protocol, but you can configure association parameters on each connector to override the settings.

• The options under Transfer timeouts determine how long the X.400 connector waits before sending an NDR for urgent, normal, and not urgent messages. Each X.400 connector uses the transfer timeout values that are configured on the X.400 MTA, but you can configure specific transfer timeout values on each connector that override these settings.
