System and method for rating unsolicited e-mail
View Patent ↗A system and method for an e-mail rating system, where e-mail senders are evaluated based upon past performance. When an individual receives an email message and determines it to be SPAM, they notify a central database, repository or server. This central server, known as a Span Detection Server or SDS, maintains a list of e-mail senders and their associated spam rating. Spam thresholds are applied to incoming e-mail by a spam filter in conjunction with the SDS. Depending upon the sender's rating as compared to these thresholds, a received message is classified as desirable, undesirable or conditional.
1. A method for rating a sender of e-mail, comprising the steps of:
receiving an e-mail from the sender;
determining if the e-mail is unsolicited spam;
sending a spam server a notification of whether the received e-mail is unsolicited spam;
maintaining a sender rating by the spam server;
placing the e-mail in a holding queue if the sender rating for the e-mail is not acceptable;
periodically checking the e-mail in the holding queue to determine if the sender of the e-mail has an acceptable rating; and
if the sender's rating is now acceptable, sending the e-mail to its intended recipient.
2. The method of claim 1 , wherein the notification includes an e-mail address of the sender.
3. The method of claim 1 , wherein the notification includes a global domain of the sender.

means for determining if the e-mail is unsolicited spam;
means for sending a spam server a notification of whether the received e-mail is unsolicited spam;
means for maintaining a sender rating by the spam server;
means for placing the e-mail in a holding queue if the sender rating for the e-mail indicates the sender is not acceptable;
means for periodically checking the e-mail in the holding queue to determine if the sender of the e-mail has an acceptable rating; and
means for sending the e-mail to its intended recipient if the sender's rating is now acceptable.
5. The system of claim 4 , wherein the notification includes an e-mail address of the sender.
6. The system of claim 4 , wherein the notification includes a global domain of the sender.
7. A method of processing e-mail, comprising the steps of:

periodically checking the e-mail in the holding queue to determine if the sender of the e-mail has an acceptable rating; and
if the sender's rating is now acceptable, sending the e-mail to its intended recipient.
8. The method of claim 7 , wherein the spam rating is acceptable if it is above a predetermined threshold.
9. The method of claim 7 , wherein the spam rating is acceptable if it is below a predetermined threshold.
10. The method of claim 7 , wherein the spam rating is not acceptable if it is undefined.
11. The method of claim 7 , wherein the step of determining a spam rating for the sender comprises the step of sending an inquiry regarding the sender to a spam server.
12. The method of claim 7 , further comprising the step of:
