    摘要: In one embodiment, a method comprises computer-implemented steps of receiving a plurality of electronic mail messages containing sender address information that is non-trusted. For each electronic mail message, information about the message is stored, and one or more receiving node identifiers in association with respective connected node identifiers is created, wherein the receiving node identifier identifies receiving mail server that received the particular message and the connected node identifier identifies a connected mail server that directly connected to the receiving node identifier to send the particular message directly to the receiving mail server. For each electronic mail message a receiving node identifier that has a largest number of connected node identifiers associated therewith is selected, and a connected node identifier that is associated with the one particular receiving node identifier that sent the particular message to the associated receiving node is selected and stored.

    摘要: A method and apparatus for managing connections, email messages, and directory harvest attacks at a server is disclosed. The server maintains a count of a parameter and compares the count to a specified maximum value, such that when the specified maximum value is met or exceeded, an action is taken by the server to limit the connections, email messages, or directory harvest attack. Actions include controlling the number of connections to the server from senders, controlling the flow of email messages injected to the server by senders, and controlling when rejection response messages are sent for invalid recipient email addresses to thwart a directory harvest attack. Senders are identified by one or more sender identifiers, which can be used to group senders together so that the same maximum value is applied collectively to all senders in the group.

    摘要: Message delivery approaches in which senders define filters with associated actions for evaluation in relation to specified messages. After creating and storing filters with specified actions, senders dispatch messages to a processing system, which evaluates the filters against the messages. If a match occurs, the processing system performs the specified actions on the messages. The processing system may send the same message multiple times to different receiving systems, and may modify the source IP address and outbound interface of the message for each receiving system. The source IP address or interface may be modified by a filter in response to external events, such as a receiving system blocking another copy of the message. A single message processing system can appear as a large number of virtual message sendingunits.

    摘要: An approach for monitoring electronic messages received at a server is disclosed. Message information for a plurality of electronic messages received at the server is determined and stored in a queue. Based on the queue, aggregate information is generated for a particular network address of a plurality of network addresses. The aggregate information is generated for each time interval of a plurality of time intervals and displayed for the plurality of time intervals. In some implementations, input from a user is received, and based on the input, a modification is made regarding how future electronic messages from the particular network address are handled by the server. In some implementations, combined aggregate information is generated for two or more network addresses and then displayed. In some implementations, aggregate policy information indicating which policies have been applied to the electronic messages is generated and displayed for the time intervals.

    摘要: A data processing apparatus can perform HTTP traffic monitoring and filtering of HTTP requests from clients and responses from servers. Example apparatus comprises a processor; a first network interface to a protected network; a second network interface to an external network; a core hypertext transfer protocol (HTTP) proxy coupled to the processor and coupled to a content cache, wherein the HTTP proxy is configured to receive an HTTP request from a client computer in the protected network, send the request to a network resource in the external network on behalf of the client, and receive an HTTP response from the network resource on behalf of the client computer; and a plurality of spyware scanning engines (SSEs), wherein each of the SSEs is coupled to stored content signatures, and wherein each of the SSEs is configured to detect a particular kind of malicious software in an HTTP response.
