A method, and corresponding system, for identifying e-mail messages as being unwanted junk or spam. The method includes converting the outputs of a set of e-mail classification tools into a standardized format, such as a probability having a value between zero and one. The standardized outputs of the classification tools are then input to a voting mechanism which uses a voting algorithm based on fuzzy logic to combine the standardized outputs into a single classification result. The use of a fuzzy logic algorithm creates a more useful result as the classifier results are not merely averaged. In one embodiment, the single classification result is itself a probability that is provided to a spam classifier or comparator that functions to compare the single classification result to a spam threshold value and based on the comparison to classify the e-mail message as spam or not spam.

Classification of e-mails stored in a storage device of an e-mail terminal into groups by the e-mail terminal.

A system for intelligently sorting e-mail comprises a client which downloads e-mails from a server. Prior to presenting the e-mails to the user, the client sorts the e-mail into classifications based upon whether the e-mail is from a personal contact, i.e. someone that that the user knows, whether the e-mail is from a commercial vendor from whom the user has indicated that he or she wishes to accept commercial e-mail, or whether the e-mail is from an unknown source. The client presents the e-mails to the user in these classifications.

A system and method for establishing temporary electronic mail (e-mail) accounts is configured to operate with classified newspaper advertising. One of the aspects of the present invention is a file handling method that automates the process of establishing the e-mail accounts through interaction with a publisher's system for taking orders for classified advertisements. Typical newspaper classified advertising comprises two or three lines of text which provide only basic information about an item for sale. With the present invention, advertisers would be offered the option of creating a special e-mail account with a duration tied to the run of the advertisement. The e-mail accounts would be used to receive inquiries about the item for sale. The e-mail account could be also be configured to auto-respond to each incoming message with additional descriptive information about the item being offered for sale. Responders could learn more about the item, and thereby avoid the necessity of calling the seller. Sellers, in turn, can avoid the problem of repeated phone calls to request additional information, and may also remain anonymous while responding to multiple inquiries.

The invention is selectively used by an Email Protection System that protects and email system from spam. This method is used if the Email Protection System classifies as spam an email connection or email message from an Email Sender. The invention is unlike other white list population methods or challenge/response systems in that it requires positive action by both the Email Sender and the Intended Email Recipient to add the Email Sender to a White List used by the Email Protection System. In accordance with the invention, the Email Protection System notifies the Email Sender of rejected email. The Email Sender uses a Request Form to request to be added to a White List. The Email Recipient confirms or denies the request. If the Email Recipient confirms, the Email Sender is added to the White List.

The invention discloses a multilevel Email classification method based on Email content. For the problem that imbalance of samples has significant impact on an Email classification effect, a mode of establishing three-level classifiers is employed. According to the mode, a naive bayes algorithm, a support vector machine and a C4.5 algorithm combined voting mode is employed in establishment of a first level classifier; a random forest algorithm is employed in the establishment of a second level classifier; and a liblinear algorithm is employed in the establishment of a third level classifier. According to the method, for design of the classifiers, a multilevel classification mode is employed; levels of the algorithms are increased; through layer by layer filtering, under the condition of ensuring a recall rate, the accuracy of the classifiers is improved gradually; the balance of positive and negative samples is increased continuously; basic balance of the Email data is realized at the last level; the final classification effect is less influenced by the imbalance of the samples; and the relatively good effect is realized in Email classification.

This disclosure relates to systems and methods for identifying fraudulent email addresses associated with an electronic payment service. In some implementations, a computing device receives an email with a prefix having a number of characters and characterized by a prefix length indicative of the number of characters in the prefix. The computing device identifies each of a number of bigrams is identified within the prefix, and determines a row and column distance for each bigram between two consecutive characters of the bigram as positioned on a keyboard. The computing device calculates a Euclidean distance between the two consecutive characters of the bigram based on the row and column distances, and determines a normalized distance based on the prefix length and an average of the Euclidean distances calculated for the number of bigrams in the prefix. The normalized distance is compared with a value to classify the email as suspicious or as not suspicious.

A method and system method for e-mail management of e-mails having embedded classification metadata. A query from an end user to access an e-mail account by an e-mail client is received. It is then determined whether the query has come from an insecure e-mail client, such as a web e-mail client. Access rules for defining classification access restrictions for the e-mail client to access e-mail in the e-mail account are retrieved when the e-mail client is determined to be insecure. The e-mail query can then be modified before sending to an e-mail server storing the email account. The query is modified based on the retrieved access rules to exclude retrieval of e-mails based upon the e-mail classification metadata.
