Abstract
A system and method are disclosed for classifying a message. The method includes receiving the message, identifying in the message a distinguishing property; generating a signature using the distinguishing property; and comparing the signature to a database of signatures generated by previously classified messages.
Claims28
A method for classifying a message, comprising:
- receiving the message;
- identifying in the message at least two distinguishing properties, wherein a domain name in the text of the message is a first distinguishing property;
- generating at least two signatures, a first signature of the at least two signatures using the domain name and a second signature using a second distinguishing property of the distinguishing properties;
- comparing the at least two signatures to a database of signatures generated by previously classified messages, wherein the second distinguishing property includes information in the text of the message that can be used by a recipient of the message to fulfill a goal of a sender of the message;
- and
- processing the message according to the comparison.

A computer readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for classifying a message, the method comprising:
- receiving the message;
- identifying in the message at least two distinguishing properties, wherein a domain name in the text of the message is a first distinguishing property;
- generating at least two signatures, a first signature of the at least two signatures using the domain name and a second signature using a second distinguishing property of the distinguishing properties;
- comparing the at least two signatures to a database of signatures generated by previously classified messages, wherein the second distinguishing property includes information in the text of the message that can be used by a recipient of the message to fulfill a goal of a sender of the message;
- and
- processing the message according to the comparison.

A system for classifying a message comprising:
- a mail client in a communication network, the mail client configured to:
- receive the message,
- identify in the message at least two distinguishing properties, wherein a domain name in the text of the message is a first distinguishing property;
- and
- generate at least two signatures, a first signature of the at least two signatures using the domain name and a second signature using a second distinguishing property of the distinguishing properties;
- and
- a mail server configured to:
- compare the at least two signatures to a database of signatures generated by previously classified messages, wherein the second distinguishing property includes information in the text of the message that can be used by a recipient of the message to fulfill a goal of a sender of the message, and
- process the message according to the comparison.
