It was common practice to restrict large messages from traversing the IMS, letting them route through an X.400 connector.

In Exchange 2000, this design feature was changed. SMTP connectors and RGCs can transmit binary attachments using the 8BITMIME and CHUNKING extended SMTP features. A common design feature in many deployments is to create connectors to allow direct traffic between two sites over a low-bandwidth ...
