Abstract

Message delivery approaches are disclosed through which senders can guarantee that their messages are desired by intended recipients. In one embodiment, a Sender agrees with a Service Operator to pay a fine for each message that is reported as an unwanted by its Recipient. For senders that agree in advance to pay such fines, Service Operators may provide preferential message routing around “spam” filters knowing that a guarantee is in place. If the Recipient reports that the message is unwanted, the Service Operator can penalize the Sender by a fine in the agreed amount, or by modifying a bond ratio value, rating, or other experience value associated with the Sender. Estimates of the complaints expected for a Sender may be used to determine the outcomes of the tests applied by the Receiver.

Claims

1. A method of facilitating transmission of a message from a sender to a receiver, comprising:

storing sender identification information in association with a penalty that a sender is willing to incur for a first message that is unwanted by the receiver;

receiving a query about whether a sender of a first message satisfies specified sending criteria;

determining whether the sender satisfies the specified sending criteria; and

sending a second message specifying whether the sender of the first message satisfies the specified sending criteria, for use by the receiver in determining whether to accept the first message;

wherein the determining step comprises determining whether the penalty is greater than a base penalty amount multiplied by the sum of (a) a number of complaints about unsolicited messages that are actually received from the sender and (b) an estimate of a number of complaints that are not yet made or never made by the receiver and any other receiver.

2. A method as recited in claim 1, further comprising refusing to accept the first message when the penalty is not greater than the base penalty amount multiplied by the sum of (a) and (b).

55. A computer-readable storage medium carrying one or more sequences of instructions for delivering electronic messages, which instructions, when executed by one or more processors, cause the one or more processors to carry out the steps of any of claims 1, 3, 5, 21, 23, 28, 29 and 37.

56. An apparatus for delivering electronic messages, comprising:

a network interface that is coupled to the data network for receiving one or more packet flows therefrom;
