Abstract

An e-mail relay provides message filtering services to an e-mail network. The e-mail relay monitors incoming communication and intercepts e-mail messages. The e-mail relay compares attributes of the messages to data derived from SPAM messages, which are stored in a SPAM database. The e-mail relay restricts the delivery of messages based on the comparison such as by restricting the delivery of messages having attributes close to those of SPAM messages from the SPAM database. The SPAM database is constructed by responding to user or administrator indications as to whether received messages are SPAM messages.

Claims

1. A method of reducing a flow of unwanted electronic messages, the method comprising:

receiving electronic messages at a relay;

supplying an intended recipient of an electronic message with an alternate message that allows the intended recipient to specify that the electronic message is unwanted, wherein the alternate message includes a URL that if selected by the intended recipient allows the intended recipient to specify that the electronic message is unwanted, and wherein the URL is unique to the electronic message;

storing the electronic message in a message store, wherein the message store stores electronic messages;

receiving a URL submission from the intended recipient, wherein the URL submission is responsive to the intended recipient'"'"'s selection of the URL, and wherein the URL submission is an indication that the electronic message is unwanted;

responsive to specification by the intended recipient that the electronic message is unwanted, prompting the intended recipient to classify the electronic message according to at least one of a plurality of pre-established categories; and

responsive to receiving the URL submission, retrieving the electronic message from the message store and adding information corresponding to the electronic message to a message database.

2. The method of claim 1, wherein the prompting is effectuated by the selection of the URL by the intended recipient.

3. The method of claim 1, wherein the plurality of pre-established categories includes an unwanted category, the method further comprising:

responsive to classification by the intended recipient that the electronic message is in the unwanted category, storing information corresponding to the electronic message in a message database that codes attributes and derived information characteristic of messages that have been determined to be unwanted.

4. The method of claim 1, wherein the plurality of pre-established categories includes a clean category, the method further comprising:

responsive to classification by the intended recipient that the electronic message is in the clean category, delivering the electronic message to the intended recipient.

5. The method of claim 1,

wherein the message store is indexed by an identifier included in the URL.

6. The method of claim 5, further comprising:

determining that the electronic message is a borderline message, wherein responsive to determining that the electronic message is a borderline message the relay quarantines the borderline message in the message store.

7. The method of claim 5,

wherein the URL submission is responsive to the intended recipient'"'"'s selection of the URL.

8. The method of claim 7, wherein retrieving the electronic message from the message store includes retrieving the electronic message from the message store by reference to the URL.

9. The method of claim 1, wherein the alternate message includes a URL that if selected by the intended recipient initiates a retrieval of information regarding the electronic message.

10. The method of claim 9, wherein the retrieved information includes at least one of a sender, subject, and message body portion of the electronic message.

11. The method of claim 9, wherein prompting the intended recipient includes responsive to selection of the URL by the intended recipient, prompting the intended recipient to classify the electronic message according to at least one of the plurality of pre-established categories.

12. A system for reducing a flow of unwanted electronic messages, the system comprising:

a relay that receives electronic messages and supplies an intended recipient of an electronic message with an alternate message that allows the intended recipient to specify that the electronic message is unwanted, wherein the alternate message includes a URL that if selected by the intended recipient allows the intended recipient to specify that the electronic message is unwanted, and wherein the URL is unique to the electronic message;

an HTTP server that prompts the intended recipient to classify the electronic message according to at least one of a plurality of pre-established categories in response to specification by the intended recipient that the electronic message is unwanted,

wherein the HTTP server receives URL submissions from users, and wherein a URL submission is an indication that the electronic message is unwanted; and

a message store that stores electronic messages, wherein the relay is configured to quarantine the electronic message in the message store, and wherein responsive to the HTTP server receiving the URL submission, the relay retrieves the electronic message from the message store and adds information corresponding to the electronic message to a message database.

13. The system of claim 12, wherein the prompt is effectuated by the selection of the URL by the intended recipient.

14. The system of claim 12, wherein the plurality of pre-established categories includes an unwanted category, the system further comprising:

the message database, wherein the message database codes attributes and derived information characteristic of messages that have been determined to be unwanted.

15. The system of claim 12, wherein responsive to the HTTP server receiving the URL submission, the relay retrieves the electronic message from the message store by reference to the URL.

16. The system of claim 12, wherein the alternate message includes the URL that if selected by the intended recipient initiates a retrieval of information regarding the electronic message, wherein responsive to selection of the URL by the intended recipient, the HTTP server prompts the intended recipient to classify the electronic message according to at least one of the plurality of pre-established categories.
