Abstract: In a distributed email system, user preferences respected more effectively by presenting messages marked for deletion to secondary messaging servers having access to user preferences. Messages marked for deletion by inbound servers are presented to secondary level servers having access to user white lists and the choice of whether to delete the suspect message is made by the secondary server.

Abstract: A method for throttling inbound email messages in an enterprise email system including a plurality of inbound mail servers and at least one management server is provided. Policies defining message event limits for each unique sender are applied to messaging events from the unique sender at each inbound server. Feedback from each of the inbound mail servers to the management server is provided. When events from a unique sender exceed a threshold, as determined by the management server using the feedback, an alert is generated and a new, more restrictive policy for the unique sender is created. The more restrictive policy is broadcast the more restrictive policy to each of the inbound mail servers.

Abstract: A seeding machine having a plurality of row units and a processing circuit. Each of the row units have a seed metering device, a seed placement device and a sensor suitable to detect a parameter related to seed placement. The seed metering device includes a metering member providing a metering action to a plurality of seeds. The seed placement device receives the seeds from the seed metering device. A seed meter drive controller receives an index signal from the sensor on the row unit as well as a reference pulse signal. The processing signal of the drive controllers compares the index signal to the reference signal. Each drive controller is selectively programmable to control an associated motor of the meter drive to produce a desired relationship between the row unit index signal and the reference signal thereby synchronizing the seed placement among two or more rows. block diagram illustrating an alternative arrangement of the meter drive and control system components.

Abstract: A method for balancing load in a network system, having a plurality of clients initiating transactions with a plurality of servers. For each transaction a host name associated with one or more servers capable of completing the transaction is specified. The client initiates a request to resolve the host name and a plurality of IP addresses are returned. The client randomly communicates with one of the IPs identified as capable of completing the transaction and reports on the success of the transaction. If multiple attempts to the same IP fail, the IP is removed from service by the client.

Abstract: Email opt-out enforcement is described. Received email messages are processed based on trust levels associated with senders of the email messages, such that email from more trusted senders is not scrutinized as much as email from less trusted senders. When a user requests to opt-out or unsubscribe from a sender's mailings, a record of the user's opt-out request is maintained. If the sender continues to send email to the user subsequent to the opt-out request, the trust level associated with the sender is adjusted to reflect a lesser degree of trust in the sender.
