1. A method for redelivery of messages having an associated message version number and attributes, for use in a messaging system comprising a folder and mailbox database for storing messages, comprising the steps of:

  • determining whether redelivery is to be carried out for a specific mailbox or folder;

    if redelivery is not to be carried out for a specific mailbox or folder, retrieving a first message from the database, ordered by version number;

    if redelivery is to be carried out for a specific mailbox or folder, locking the specific mailbox or folder such that the redelivery process will have exclusive access to it, and then retrieving a first message from the mailbox or folder, ordered by version number;

    determining whether redelivery is being specifically requested, or forced, by the mail administrator;

    if redelivery is being forced, setting the message version to a number which is different from a current version;

    if redelivery is not being forced, determining whether the version of the message is equal to a current version;

    if the version of the message is not equal to the current version, preparing the database for message redelivery by deleting attributes associated with said message; and

    delivering the message.
