transport dumpster

In Exchange Server 2007, a feature of the Hub Transport server role that is only enabled for cluster continuous replication (CCR). The transport dumpster provides an administrator with the option to configure CCR so that the clustered mailbox server will automatically come online on another node, with limited amount of data loss. When this happens, the system automatically redelivers all the recent e-mail messages sent to users on this server by taking advantage of the transport dumpster where these e-mail messages are still stored.
