Thus, it would take considerable heuristics to figure out which are duplicative e.g., PMW1@host might be the same mailbox as Pete-Weiss@host . Did those folks opt-in to the new (merge) list? If not, maybe that would be the way to go? Or, maybe RENEWAL processing could be used? Follow-ups to lstOWN-l. /Pete
