Abstract

A method for controlling a message from a sender. A referee can evaluate a credential associated with a message to determine it'"'"'s desirability to the intended recipient, and take an action based upon the results of the determination. A sender that includes a trusted component can send a credential with the message, and the message can be controlled without a referee.

Claims

1. A method for controlling a message from a sender, the message having an intended recipient, including:

receiving at a referee at least part of a credential that is associated with a message that was sent to an intended recipient, the credential being forwarded from the intended recipient to the referee after the credential is received by the intended recipient from the sender;

determining at the referee if the message is spam by evaluating the at least part of the credential, wherein evaluating includes identifying a predetermined desirability rating or indicator associated with a digital certificate that is associated with the message; and

performing an action with respect to the message based upon the results of the evaluation.

2. The method of claim 1, wherein the credential includes a digital signature of the sender of the message.

3. The method of claim 1, wherein the credential includes a digital certificate.

4. The method of claim 1, wherein the message includes an e-mail message.

5. The method of claim 1, wherein the message includes a telephonic message.

6. The method of claim 1, wherein the message includes an instant message.

7. The method of claim 1, wherein the message includes a videoconferencing message.

8. The method of claim 1, wherein the message includes a fax message.

9. The method of claim 1, wherein performing an action with respect to the message includes causing the message to be blocked.

10. The method of claim 1, wherein performing an action with respect to the message includes causing a message warning to be sent.

11. The method of claim 1, wherein performing an action with respect to the message includes causing a message desirability rating or indicator to be sent.

12. The method of claim 1, wherein performing an action with respect to the message includes causing the message to be forwarded.

13. The method of claim 1, wherein evaluating the credential includes verifying a digital signature associated with the message.

14. The method of claim 1, wherein the rating or indicator associated with the digital certificate is stored in a distributed database.

15. The method of claim 1, wherein evaluating the credential includes verifying a Message Authentication Code associated with the message.

16. The method of claim 1, further including determining a desirability of the message based upon the destination address of the message.

17. The method of claim 1, further including determining a desirability of the message based upon at least part of the body of the message.

18. The method of claim 1, further including determining a desirability of the message, wherein determining a desirability of the message includes applying a message status determination rule, including determining a desirability of the message from a status value stored in a database, the status value being associated with an address of the sender.

19. The method of claim 1, wherein the message includes an identifier of the intended recipient.

20. The method of claim 18, wherein the status value associated with the address of the sender is dependent on a time of a day.

21. The method of claim 1, wherein evaluating the at least part of the credential includes determining a desirability rating for the message, wherein a range of the desirability rating is from a minimum value to a maximum value, wherein at least one value is allowed between the minimum and maximum value.

22. The method of claim 21, further comprising:

receiving, at the referee from the intended recipient, a specification regarding one or more actions to be performed when the desirability rating has a certain range of values,

wherein performing the action with respect to the message based upon the results of the evaluation is based at least in part on the specification received from the intended user.

23. The method of claim 1, further comprising:

receiving, at the referee from other intended recipients, complaints regarding the message; and

classifying the message as having a low desirability rating when a number of complaints exceeds a threshold.

24. The method of claim 23, further comprising rating the complaints, wherein a low rating is given to a high volume of complaints from a single source.

25. The method of claim 3, wherein the digital certificate is one of a plurality of certificates associated with the sender, wherein each certificate is associated with a different sender class, each being subject to different restrictions.

26. The method of claim 25, further comprising filtering the message based on the sender certificate class.

27. A method for controlling a message from a sender, the message having an intended recipient, including:

receiving at a referee at least part of a credential that is associated with a message that was sent to an intended recipient, the credential being forwarded from the intended recipient to the referee after the credential is received by the intended recipient from the sender;

determining at the referee if the message is spam by evaluating the at least part of the credential;

determining a desirability of the message based upon the destination address of the message; and

performing an action with respect to the message based upon the results of the evaluation.

28. The method of claim 27, wherein the credential includes a digital certificate.

29. The method of claim 27, wherein the message includes at least one of an e-mail message or an instant message.

30. The method of claim 27, wherein the message includes a at least one of a telephonic message, a videoconferencing message, or a fax message.

31. The method of claim 27, wherein performing an action with respect to the message includes causing the message to be blocked.

32. The method of claim 27, wherein performing an action with respect to the message includes causing a message warning to be sent.

33. The method of claim 27, wherein performing an action with respect to the message includes causing a message desirability rating or indicator to be sent.

34. The method of claim 27, wherein performing an action with respect to the message includes causing the message to be forwarded.

35. The method of claim 27, wherein evaluating the credential includes verifying a digital signature associated with the message.

36. The method of claim 27, wherein determining a desirability of the message includes applying a message status determination rule, including determining a desirability of the message from a status value stored in a database, the status value being associated with an address of the sender.

37. The method of claim 36, wherein the status value is dependent on a time of a day.

38. A method for controlling a message from a sender, the message having an intended recipient, including:

receiving at a referee at least part of a credential that is associated with a message that was sent to an intended recipient, wherein the credential includes a digital certificate, the credential being forwarded from the intended recipient to the referee after the credential is received by the intended recipient from the sender, wherein the digital certificate is one of a plurality of certificates associated with the sender, wherein each certificate is associated with a different sender class, each being subject to different restrictions;

determining at the referee if the message is spam by evaluating the at least part of the credential; and

performing an action with respect to the message based upon the results of the evaluation.

39. The method of claim 38, further comprising filtering the message based on the sender certificate class.
