Methods and systems for detecting suspicious traffic patterns in electronic communications are provided. According to one embodiment, an electronic mail (email) message is received by a mail filter (milter), which evaluates a traffic pattern represented by the email message by scanning information associated with the email message and comparing it to information associated with one or more traffic analysis profiles. If the email message is identified by the milter as being inconsistent with normal email traffic patterns as represented by the one or more traffic analysis profiles, then the milter causes the email message to be handled in accordance with an email security policy associated with suspicious traffic patterns. For example, in the context of an outbound message, the originator may be alerted to a factor contributing to the identification and the originator may be provided with an opportunity to address the factor.

A system and method is proposed for managing email messages across a network. The system provides multiple means of verifying an originating sender of email. In addition, the system automatically generates unique email addresses as a means mask the email address of an original sender and shield users from unwanted email. The system may also be configured to block email security threats (e.g. phishing, spear phishing, etc.). Further, the system provides means of processing email messages to enable encryption, spam detection, geographical location identification of users, and social networking.

A method of establishing an e-mail secure transmission link between an initiator and a responder for the transmission of secure e-mail messages over a network comprising creation of a unique initiator designator or number, generation of a unique initiator exchange key component including the unique initiator designator or number, transmission of a request from the initiator to the responder to establish the e-mail secure transmission link and the unique initiator exchange key component, acceptance of the request by the responder to establish the e-mail secure transmission link, creation of a unique responder designator or number, combining of the unique responder designator and the unique initiator exchange key component to create a unique initiator / responder exchange key at the responder site, generation of a unique responder exchange key component including the unique responder designation, transmission of the unique responder exchange key component from the responder to the initiator, combining the unique initiator designator with the unique responder exchange key component to create the unique initiator / responder exchange key at the initiator site and to establish the e-mail secure transmission link to send and receive e-mail between the initiator and the responder exchange with the unique initiator / responder exchange key.

A method includes, in response to receiving an email message, detecting one or more artifacts within an email message, wherein each of the artifacts is associated with a payload; for each artifact, generating, a descriptor object representing the artifact that does not include the payload, so that the processor is prevented from accessing the payload via the descriptor object; and at least one payload button based on the payload associated with the artifact for causing the payload to be transmitted to an external system for analysis of the payload; and presenting an artifact dashboard in a graphical user interface (GUI) rendered on a display of the email security system, the artifact dashboard displaying, for each artifact, the descriptor object representing the artifact and the at least one payload button based on the payload associated with the artifact.

A system and method are disclosed for providing an extensible email having rich, interactive browser capabilities. The system includes a service provider for receiving extensible emails from a third party platform and presenting the emails to a user's computing device. The extensible email includes URL metadata which allows a mail user agent to fetch and run code from a third party server in order to generate the extensible email. A secure sandbox ensures that the third party code does no damage to the service provider system or the user's computing system.
