Abstract: A multi-stage email interception method. First, an email message is received. Then, the receiving number corresponding to the email message is queried from an array according to the related information of the email message. The email message is rejected if the receiving number is higher than a first setting value and the email message conforms to the email characteristics recorded in a specific email record; the email message is accepted first and then deleted if the receiving number is higher than a second setting value and the email address of the recipient of the email message does not appear in the recipient field of the email message; and the email message is accepted and forwarded to a specific mailbox if the receiving number is lower than the second setting value and more than a third setting value and the email address of the recipient of the email message does not appear in the recipient field of the email message.

Abstract: A system, method and program product for diagnosing, controlling and collecting information from devices. Information regarding events of each one of a plurality of target applications executing in an application unit is collected and formatted into one of multiple data formats for transmission through one of multiple communication protocols at the request of each of the target applications, through an interface. The event information for a particular target application is formatted and transmitted according to a combination of a data format and communication protocol requested by the target application. The transmission of data representing the event information is handled in at least two levels of software classes, with at least one abstract software class having a declared virtual function and two or more software classes derived from the at least one abstract class and having definitions of the function for communicating the event information through specified communication protocols.

Abstract: A method and device thereof for managing messages received at a bridging device. A bridging device receives a first message comprising a first contact information and a first distance vector representing a first number of hops the first message has traversed. The first distance vector is compared to a stored second distance vector corresponding to a stored second contact information for the remote electronic device, wherein the second contact information and second distance vector are provided by a second message. The second distance vector represents a second number of hops the second message has traversed. Provided the first number of hops is greater than the second number of hops, the first message is discarded. Alternatively, provided the first number of hops is not greater than the second number of hops, the second contact information and second distance vector are discarded and the first contact information and first distance vector are stored on a computer- readable memory of the bridging device.
