Establishing secure, mutually authenticated communication between a trusted network and a perimeter network. Servers on the perimeter network may be securely and automatically configured to communicate with the trusted network. Servers not functioning properly may be stopped from communicating with the other servers. Credential information relating to a perimeter server may be automatically, and regularly, updated without intervention.

Establishing secure, mutually authenticated communication credentials

Automatically sending configuration information from a trusted network to a perimeter network. Master servers residing in the trusted network are adapted for administering a distributed directory service containing configuration information. Edge servers residing in the perimeter network are adapted for using a local directory service local to each edge server. Edge-connected bridgehead servers residing in the trusted network are adapted for replicating the configuration information from the trusted network to the perimeter network. Replicating the configuration information to the perimeter network by trusted servers acquiring leases on edge servers is also disclosed.

Updating configuration information to a perimeter network

In a distributed electronic messaging system authorized information comprising metadata concerning a message is passed along from one mail server to another mail server. A receiving computer determines if the sending computer has the necessary authorizations to pass along the metadata. If so, the authorized information is passed along with the message body, enabling repetitious actions to be eliminated. If the sending computer is not authorized to pass along the metadata, the metadata is stripped off the message, changed or annotated.

Mail server coordination activities using message metadata

The coordination and execution of chores in a multiprocessing environment. The coordination of chores is accomplished utilizing a compiler generated correlation that relates blocks of code that execute chores and blocks of code in which the chore can be realized. By tracking the execution of the program and using the compiler-generated correlation, chores can be identified for the currently executing code.

Coordinating chores in a multiprocessing environment using a compiler generated exception table

Various technologies and techniques are disclosed for providing concurrent exception handling. When one or more exceptions are received from concurrent workers, one or more exception handler functions are supplied. For each respective exception in the exception results, determine if the respective exception is one of a kind of exceptions handled by the one or more exception handler functions. If the respective exception is one of a kind handled by the exception handler functions, then run a particular handler of the exception handler functions and mark the respective exception as handled. Any unhandled exceptions are then processed appropriately. In one implementation, a collection of input data is processed to produce a collection of output results, with the exceptions being interleaved with other output results. In another implementation, a particular exception is selected that represents the multiple exceptions. The selected one particular exception is then thrown.

Concurrent handling of exceptions in received aggregate exception structure with supplied exception handlers and marking handled exceptions

A schema for a rule transport engine to be applied to an email having multiple recipients. The schema defines a rule which executes one or more specific actions for a particular recipient or a particular group of recipients receiving a message instance of a bifurcated message when the message meets certain conditions.

Email transport rule per-recipient condition

Various technologies and techniques are disclosed for providing concurrent exception handling. Exceptions that occur in concurrent workers are caught. The caught exceptions are then forwarded from the concurrent workers to a coordination worker. The caught exceptions are finally aggregated into an aggregation structure, such as an aggregate exception object. This aggregation structure is rethrown and the individual caught exceptions may then be handled at a proper time.

Concurrent exception handling using an aggregated exception structure

A transmitting gateway may utilize a retrieved domain-specific key to secure an outbound message, and a receiving gateway may utilize another retrieved domain-specific key to authenticate and validate the secured message.

Key distribution for secure messaging

Propagating messaging preferences of one or more users from a recipient mailbox to a perimeter network administering e-mail content blocking and routing. A content filtering application located outside a trusted network receives messaging preferences information from within the trusted network regarding the mail recipients. This messaging preferences information may be utilized to allow certain pre-authorized messages from particular senders to bypass content filtering. Moreover, the messaging preferences information may be hashed to further protect the information on the perimeter network and to speed in review and comparison of the messaging preferences information. In addition, other types of user-specific information may be propagated to the perimeter network for use with other applications other than messaging.

Perimeter message filtering with extracted user-specific preferences

Throwing one selected representative exception among aggregated multiple exceptions of same root cause received from concurrent tasks and discarding the rest

Systems and methods are described which provide enhanced stability, increased predictability, reduced transmission costs, and which conserve bandwidth in routing messages over computer networks. The systems and methods further include providing improved transmission of messages wherein the messages are transmitted to nodes closest to a target delivery node. If delivery is possible to a target node, the message transmission stops at the point of failure in the network, wherein delivery to the target node is accomplished at a later time or the message is returned to the sender.

Failover systems and methods for providing redundant backup of data transmitted over a network to provide transport high availability of electronic data. The present invention relates to creating redundant backup copies of electronic data as well as transmission of the backup copies over a network in the event of a failure of a network component.

Transport high availability

A discovery secret is transmitted from the source domain to the correspondent domain. The discovery secret includes a data element specific to the correspondent domain and. The discovery secret includes a source domain address to which the correspondent domain is permitted send a message in order to determine that a potential correspondent has compatible secure email technology so that a link between the source domain and the correspondent domain may be established. The discovery secret is received by the correspondent domain including receiving the data element and the source domain address. An invitation is transmitted from the correspondent domain to the source domain address. The invitation includes the data element or an element corresponding to the data element. The source domain initiates a process to establish a link with the correspondent domain upon receipt by the source domain of the invitation.
