US Classification:

709206, 709245, 713176

Abstract:

A system and method for sending email. The method includes the steps of receiving: an email address including a destination domain from a user; prior to sending a message to the destination domain, determining whether the destination domain will receive email; and providing an indication to the user that the email may not be deliverable to the address. In one embodiment, the step of determining includes maintaining a list of problematic destination domains and checking the destination domain against said list.

US Classification:

709227, 709249, 370232, 370259, 713193

Abstract:

Publicly accessible linking information is to establish a trusted relationship between reciprocally linked entities controlling web resources, such as websites or web logs. A method of establishing a trust relationship between two entities identifying a user-installed link to a second web resource in a first web resource. Next, the method determines when a reciprocal link is made in the second web resource directed to the first web resource and creates a trust relationship between the entities based on the reciprocal link.

International Classification:

G06F 15/16

US Classification:

709206

Abstract:

In a distributed email system, user preferences respected more effectively by presenting messages marked for deletion to secondary messaging servers having access to user preferences. Messages marked for deletion by inbound servers are presented to secondary level servers having access to user white lists and the choice of whether to delete the suspect message is made by the secondary server.

International Classification:

G06F 15/16

US Classification:

709206, 709207

Abstract:

Methods for assisting email users manage email messages received in an email account. An event is triggered by an action performed by an email user with respect to an email message in an email account. The event identifies an entity associated with the email message (e. g. , sender address, domain, keyword, etc. ). A determination is made whether to assist the user manage their email based on a heuristic. The heuristic assigns weights based on prior events associated with the same entity to determine whether the user is interested in receiving emails from the sender. Based on the heuristics, the method may add the sender to the user's block-list or unsubscribe the user from a mailing list.

US Classification:

726 3, 726 2, 713188, 709223, 709224, 709225

Abstract:

Network entities controlling a set of nodes may vary by trustworthiness, such as tolerance for nodes that send spam, distribute malware, or perform denial-of-service attacks. A device receiving such activities may identify a trust rating of the network entity and apply appropriately stringent filtering (such as spam evaluation) to activities received from nodes controlled by the network entity. However, a poor trust rating of a network entity may subject a legitimate node controlled by the network entity to inefficiently or unfairly stringent activity filtering. Instead, the device may evaluate the activities of a particular node, assign a trust rating to the node, and if the trust rating of the node is higher than the trust rating of the network entity, apply less stringent activity filtering to the activities of the node, thereby “rescuing” the node from the more stringent activity filtering applied to the other nodes of the network entity.

US Classification:

726 22, 726 4, 726 14, 726 18, 713154, 709206

Abstract:

Detection of user accounts associated with spammer attacks may be performed by constructing a social graph of email users. Biggest connected components (BCC) of the social graph may be used to identify legitimate user accounts, as the majority of the users in the biggest connected components are legitimate users. BCC users may be used to identify more legitimate users. Using degree-based detection techniques and PageRank based detection techniques, the hijacked user accounts and spammer user accounts may be identified. The users' email sending and receiving behaviors may also be examined, and the subgraph structure may be used to detect stealthy attackers. From the social graph analysis, legitimate user accounts, malicious user accounts, and compromised user accounts can be identified.

Abstract:

A method of displaying email messages to a user is provided. Spam classification information and meta data is associated with email messages received for a user. Email message summary information is displayed in a user interface based on whether the meta data associated with the message meets or exceeds a threshold display level for the summary information. The user provides input via the user interface which is an indication to change the threshold display level and the change is dynamically displayed.
