REAL-TIME AD-HOC SPAM FILTERING OF EMAIL
First Claim
1. A network device to manage a delivery of a message over a network, comprising:
- a transceiver to send and receive data over a network; and
a processor that is operative to perform actions, comprising;
performing a first pass analysis on a plurality of messages, which have been previously sorted into a plurality of different message folders by a first message filter, using a second, multi-pass message filter that is configured to generate a classification model based on the first pass analysis, wherein the generated classification model is configured to reside exclusively in a non-persistent memory location;
using the generated classification model with the second, multi-pass message filter to perform a second pass on the sorted plurality of messages, to generate a misclassification identification of sorted messages;
displaying the misclassification identification of sorted messages such that at least one misclassified message can be moved to a different message folder based on the misclassification identification; and
purging the generated classification model from non-persistent memory location.

Abstract
Embodiments are directed towards employing a multi-pass ad-hoc spam message filtering approach that dynamically generates a temporary classifier during a first pass based on a result of a previously applied message filter that sorts messages into various folders for a user. The first pass scans messages in a user'"'"'s mail folders, and reads various information within the messages, including, but not limited to sender information, headers, including a subject, an originating network address, message contents, attachments, and the like. After creating a classification model, the classifier with its model is used in a second pass on the message folders to retrospectively inspect the messages and present to the user a list of messages that might be misclassified. The classification model is maintained within memory on a user'"'"'s client device, as memory resident only, and is not stored on disk or within another persistent data store.

6. A processor readable storage medium that includes data and instructions, wherein the execution of the instructions on a computing device provides for managing messages by enabling actions, comprising:
-
receiving a plurality of messages; sorting the plurality of messages into a plurality of different message folders using a first message filter, wherein the first message filter is configured to store first classification data in a persistent store; executing a first pass of a multi-pass message filter on the sorted plurality of messages to train the multi-pass message filter by generating second classification data, wherein the second classification data is configured to reside exclusively in a non-persistent memory store; using the second classification data, executing a second pass of the multi-pass message filter on the sorted plurality of messages to score each message; identifying any message in the plurality of messages that based on the message'"'"'s respective score indicates that the message is sorted into an incorrect message folder; and providing a display of information associated with any message identified as stored into the incorrect message folder, such that a user is enabled to move the identified message to another message folder. - View Dependent Claims (7, 8, 9, 10, 11)

12. A method for managing a message delivery, comprising:
-
receiving a plurality of messages; sorting the plurality of messages into a plurality of different message folders using a first message filter, wherein the first message filter is configured to store first classification data in a persistent store; executing, on a client device, a first pass of a multi-pass message filter on the sorted plurality of messages to train the multi-pass message filter by generating second classification data, wherein the second classification data is configured to reside exclusively in a non-persistent memory store; using the second classification data, executing on the client device a second pass of the multi-pass message filter on the sorted plurality of messages to score each message; identifying any message in the plurality of messages that based on the message'"'"'s respective score indicates that the message is sorted into an incorrect message folder; and providing a display of information associated with any message identified as stored into the incorrect message folder, such that a user is enabled to move the identified message to another message folder. - View Dependent Claims (13, 14, 15, 16)

17. A system for enabling a communications over a network, comprising:
-
a network device configured to perform actions, including; receiving a plurality of messages; assigning the plurality of messages to a plurality of different message folders using a first message filter, wherein the first message filter is configured to store first classification data in a persistent store; and communicating the messages over the network to the plurality of different message folders; and a client device configured to perform actions, including; executing a first pass of a multi-pass message filter on the sorted plurality of messages to train the multi-pass message filter by generating second classification data, wherein the second classification data is configured to reside exclusively in a non-persistent memory store at the client device; using the second classification data, executing a second pass of the multi-pass message filter on the sorted plurality of messages to score each message; identifying any message in the plurality of messages that based on the message'"'"'s respective score indicates that the message is sorted into an incorrect message folder; and providing a display of information associated with any message identified as stored into the incorrect message folder, such that a user is enabled to move the identified message to another message folder. - View Dependent Claims (18, 19, 20)
