A system and method for circumventing schemes that use duplication detection
to
detect and block unsolicited e-mail (spam.) An address on a list is assigned to
one of m sublists, where m is an integer that is greater than one. A set of m different
messages are created. A different message from the set of m different messages
is sent to the addresses on each sublist. In this way, spam countermeasures based
upon duplicate detection schemes are foiled.
