Scope:
All Barracuda Spam and Email Security Gateway, All Firmwares

Answer:
From firmware version 5.x and later, a new major revision of the Reputation Definition is required. During the initial download and installation of the new Reputation Definition the device may respond with a ?451 Internal Error? when messages are attempting to be sent to the device. Once the definition install has been completed normal operation should commence.
