Abstract

A system and method are disclosed for routing a message through a plurality of test methods. The method includes: receiving a message; applying a first test method to the message; updating a state of the message based on the first test method; and determining a second test method to be applied to the message based on the state.

Claims

1. A method for routing a message through a plurality of test methods, the method comprising:

receiving a message at a network interface of a router via a communication network from an external computing device; and

executing instructions stored in memory, wherein execution of the instructions by a processor;

applies a first test method to the received message, wherein application of the first test method results in an indeterminate classification of the received message,

selects one or more next test methods from a plurality of next test methods for application to the received message until all of the next test methods have been selected or until a determinate classification of the received message results from application of the selected one or more next test methods, wherein a first next test method that is more likely to result in a determinate classification is selected over a second next test method that is less likely to result in a determinate classification, and

providing the received message for delivery to a user when all next test methods have been selected for application to the received message and application of the next test methods results in an indeterminate classification of the received message, wherein the indeterminate classification of the received message corresponds to an indication that the received message does not include spam.

2. The method of claim 1, wherein at least one of the first test method and the one or more next test methods correspond to a user preference.

3. The method of claim 2, wherein the user preference was selected by the user before the message was received.

4. The method of claim 1, wherein results from each of the first test method and the one or more next test methods are provided to a neural network and the neural network updates at least one criteria for selecting at least one next test method of the one or more next test methods based on at least one result of the results provided to the neural network.

5. The method of claim 1, wherein the memory further includes a lookup table regarding a plurality of possible states of the received message.

6. The method of claim 5, wherein the lookup table is adaptive in accordance with at least one of the first test method and the one or more next test methods that have been determinative in the past.

7. The method of claim 5, wherein the plurality of possible states of the received message include correspond to a message classification that includes the indeterminate classification.

8. A non-transitory computer-readable storage medium having embodied thereon a program executable by a processor for performing a method for routing a message through a plurality of test methods, the method comprising:

receiving a message at a network interface of a router via a communication network from an external computing device; and

executing instructions stored in memory, wherein execution of the instructions by a processor;

applies a first test method to the received message, wherein application of the first test method results in an indeterminate classification of the received message,

selects one or more next test methods from a plurality of next test methods for application to the received message until all of the next test methods have been selected or until a determinate classification of the received message results from application the selected one or more next test methods, wherein a first next test method that is more likely to result in a determinate classification is selected over a second next test method that is less likely to result in a determinate classification, and

providing the received message for delivery to a user when all next test methods have been selected for application to the received message and application of the next test methods results in an indeterminate classification of the received message, wherein the indeterminate classification of the received message corresponds to an indication that the received message does not include spam.

9. The non-transitory computer-readable storage medium of claim 8, wherein at least one of the first test method and the one or more next test methods correspond to a user preference.

10. The non-transitory computer-readable storage medium of claim 9, wherein the user preference was selected by the user before the message was received.

11. The non-transitory computer-readable storage medium of claim 8, wherein results from each of the first test method and the one or more next test methods are provided to a neural network and the neural network updates at least one criteria for selecting at least one next test method of the one or more next test methods based on at least one result of the results provided to the neural network.

12. The non-transitory computer-readable storage medium of claim 8, wherein the memory further includes a lookup table regarding a plurality of possible states of the received message.

13. The non-transitory computer-readable storage medium of claim 12, wherein the lookup table is adaptive in accordance with at least one of the first test method and the one or more next test methods that have been determinative in the past.

14. The non-transitory computer-readable storage medium of claim 12, wherein the plurality of possible states of the received message include correspond to a message classification that includes the indeterminate classification.

15. A system for routing a message through a plurality of test methods, the system comprising:

a router comprising a network interface that receives a message via a communication network from an external computing device;

a processor that executes instructions stored in memory, wherein execution of the instructions by the processor;

applies a first test method to the received message, wherein application of the first test method results in an indeterminate classification of the received message,

selects one or more next test methods from a plurality of next test methods for application to the received message until all of the next test methods have been selected or until a determinate classification of the received message results from application of the selected one or more next test methods, wherein a first next test method that is more likely to result in a determinate classification is selected over a second next test method that is less likely to result in a determinate classification, and

providing the received message for delivery to a user when all next test methods have been selected for application to the received message and application of the next test methods results in an indeterminate classification of the received message, wherein the indeterminate classification of the received message corresponds to an indication that the received message does not include spam.

16. The system of claim 15, wherein at least one of the first test method and the one or more next test methods correspond to a user preference.

17. The system of claim 16, wherein the user preference was selected by the user before the message was received.

18. The system of claim 15, wherein results from each of the first test method and the one or more next test methods are provided to a neural network and the neural network updates at least one criteria for selecting at least one next test method of the one or more next test methods based on at least one result of the results provided to the neural network.

19. The system of claim 15, wherein the memory further includes a lookup table regarding a plurality of possible states of the received message.

20. The system of claim 19, wherein the lookup table is adaptive in accordance with at least one of the first test method and the one or more next test methods that have been determinative in the past.
