Abstract

A method and system for preventing routing maelstrom loops of automatically routed electronic mail which is operational with intelligent agents and computer-processor hardware components, and includes a software based solution comprising a processor readable code of instructions. The code of instructions generally comprise a routine for tagging processed e-mail message with a system generated special identifying tag revealing each source subscriber, a routine for ascertaining whether a received message intended for automatic routing contains any special tag and a corresponding routine for deciding whether any of the special tags contain the current source subscriber's identification before exercising any routing rules against the message. If the subscriber's ID is listed in the particular e-mail being routed, then the system of the invention determines that a complete loop has been made and terminates further transmission since the next target subscriber has already received the message. Otherwise, the routing of the mail is executed.
