Spam detector with challenges
First Claim
1. A system facilitating detection of unsolicited e-mail, comprising:
- an e-mail component that receives or stores messages and receives or computes associated probabilities that the e-mail messages are spam; and
, a challenge component that sends a challenge to an originator of an e-mail message having an associated probability greater than a first threshold.

Abstract
A system and method facilitating detection of unsolicited e-mail message(s) with challenges is provided. The invention includes an e-mail component and a challenge component. The system can receive e-mail message(s) and associated probabilities that the e-mail message(s) are spam. Based, at least in part, upon the associated probability, the system can send a challenge to a sender of an e-mail message. The challenge can be an embedded code, computational challenge, human challenge and/or micropayment request. Based, at least in part, upon a response to the challenge (or lack of response), the challenge component can modify the associated probability and/or delete the e-mail message.

11. A system facilitating detection of unsolicited messages, comprising:
-
a mail classifier that receives an incoming message and classifies the incoming message as spam or a legitimate message; and
,a challenge component that sends a challenge to a sender of the message if the message is classified as spam. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A system facilitating detection of unsolicited e-mail, comprising:
-
a mail classifier that receives an incoming e-mail message and classifies the incoming e-mail message as spam, questionable spam or legitimate e-mail; and
,a challenge component that sends a challenge to a sender of an e-mail message classified as questionable spam. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29)

30. A method for detecting unsolicited e-mail, comprising:
-
sending a challenge to a sender of an e-mail message classified as questionable spam;
receiving a response to the challenge; and
,modifying the classification of the e-mail message based, at least in part, upon the response to the challenge. - View Dependent Claims (31, 32)

33. A method for responding to e-mail challenges, comprising:
-
receiving challenges to e-mail messages;
ordering the challenges based, at least in part, upon a message with fewer challenges processed before a message with more challenges;
processing the challenge of the message with fewer challenges; and
,sending a response to the challenge of the message with fewer challenges.

34. A data packet transmitted between two or more computer components that facilitates unsolicited e-mail detection, the data packet comprising:
a data field comprising information associated with a challenge, the challenge being based, at least in part, upon an associated probability that an e-mail message is spam.

35. A computer readable medium storing computer executable components of a system facilitating detection of unsolicited e-mail, comprising:
-
a mail classifier component that receives e-mail messages and determines an associated probability that the e-mail message is spam; and
,a challenge component that sends a challenge to a sender of an e-mail message having an associated probability greater than a first threshold.

36. A system facilitating detection of unsolicited e-mail, comprising:
-
means for determining an associated probability that an e-mail message is spam; and
,means for sending a challenge to a sender of an e-mail message having an associated probability greater than a first threshold.
