Abstract
In a system which delivers documents which fulfill a delivery condition set by a user, when a request to change the delivery condition is entered, the system notifies the user what documents would be no longer delivered after the change so that the user can evaluate the change of the delivery condition. To be more concrete, documents which have been delivered to users are preserved and, when it is requested by a user to change the user'"'"'s delivery condition, the system applies the changed delivery condition to the preserved documents and presents what documents would be no longer delivered to the user due to inconsistency with the new delivery condition.
