patent claim #6,643,686

System and method for counteracting message filtering

SUMMARY OF THE INVENTION

An embodiment of the present invention includes a system and method for
counteracting schemes for blocking unsolicited e-mail (spam) that are based
upon duplicate detection. An e-mail recipient's address on a list is
assigned to one of m sublists, where m is an integer greater than 1. m
different messages are created. A different the message of the m messages is
sent to the addresses on each sublist. In this way, spam countermeasures
based upon duplicate detection schemes are foiled.
