Configuring Message Routing

X.400 Connector

You can use an X.400 connector to establish an X.400 messaging route between two Exchange routing groups or between an Exchange routing group and a foreign X.400 system. An X.400 messaging route defines the path that an X.400 message follows to reach its final destination. It allows the Message Transfer Agent (MTA) in either routing groups or systems to communicate. You can configure multiple X.400 connectors to support different transport types, such as TCP/IP or X.25.

Using an X.400 connector to link routing groups together is desirable only if X.400 connectivity exists and there is a severe shortage of network bandwidth between two locations. The message payload of a large attachment transferred over an X.400 connector is less than the same message payload that is base 64-encoded for SMTP transfer.

For an X.400 connector, routing functionality and transfer of link state information are the same as with a Routing Group connector; however, unlike a Routing Group connector, only a single host can be defined for the local and remote bridgehead servers. This means that load balancing can be achieved only with multiple X.400 connectors.

The X.400 connector is provided primarily for the following purposes:
