Abstract: An email security system is described that allows users within different organizations to securely send email to one another. The email security system provides a federation server on the Internet or other unsecured network accessible by each of the organizations. Each organization provides identity information to the federation server. When a sender in one organization sends a message to a recipient in another organization, the federation server provides the sender's email server with a secure token for encrypting the message to provide secure delivery over the unsecured network.

Abstract: Described herein is technology for, among other things, detecting a data item that causes a process running within a computer system processing multiple data items to crash when the data item is processed. The technology involves associating a unique identifier with each data item prior to the data item being processed. If the processing of a particular data item causes a crash, the particular data item's unique identifier is stored in a persistent storage and the process is restarted in response to the crash. Once the process has restarted, the unique identifier is read from the persistent storage and the data item associated with the unique identifier is flagged as the data item that caused the process to crash.

Abstract: A computer implemented method comprising receiving a connection, determining a credit status of the source of the connection, setting a response delay time length corresponding to the credit status of the source, and waiting the response delay time length before sending a response. A hacker or malicious user using a source may make use of the fact a server application adds a delay to negative responses to equate a time delay with a negative response and therefore drop a connection upon discovering a time delay. A tarpitting component may discourage or defeat such hacker or malicious user behavior by storing the identity of the source and adding the delay to negative responsive to subsequent connections from the source.

Abstract: The present invention extends to methods, systems, and computer program products for e-mail envelope journaling. A server determines that an entity's (e.g., a recipient revealed form an expanded distribution list) home mailbox store has envelope journaling enabled and specifies a journaling mailbox address. The server sets a journaling property in an e-mail message identifying that the e-mail message is to be journaled. The server adds the journaling mailbox address specified by the entity's home mailbox store to the journaling property. The server sends envelope journaling information through an envelope protocol extension to the journaling mailbox addresses specified in the journaling property. The server sends the e-mail message to one or more recipients specified in the e-mail message and journaling mailbox addresses specified in the journaling property.
