Patent ID: 7543053

Claim:
A computer implemented system that facilitates classifying messages in connection with spam prevention, comprising: memory operatively coupled to a processor; a component that receives a set of the messages; a first classification component that identifies a subset of the messages as SPAM or flagged for further analysis, and temporarily delays further classification of the subset of messages; and a second classification component that after a delay period classifies the subset of messages by employing a filter that is updated during the delay period based at least in part on one or more learning techniques that are employed to receive additional data associated with the subset of messages during the determined delay period, the additional data includes data based on an analysis of the subset of messages, the delay period is dynamically determined based in part on at least one of a probability that the set of messages are spam, a time of next filter update, a time of next filter download and a level of uncertainty associated with the subset of messages, the determined delay period is reduced when determined that the subset of messages have been quarantined by one or more server filters, the memory retains at least a portion of at least one of the component, the first classification component or the second classification component.
