Auto-Elimination of Duplicate In-Basket Items in Electronic Mail

      Users of electronic mail systems are often burdened with the
need to manually handle duplicates of notes and letters that they
have received.  This document describes a technique that will
automatically eliminate, duplicate notes or letters from being
received into the recipient's in-basket.

      The in-basket function of an electronic mail system must have
two containers that provide the information required to implement
this function:

o   The first is the Active Notes & Letters(1.1) container which
    holds the notes and letters received by the recipient.

o   The second is the Inactive Notes & Letters(1.2) which is a list
    of the Unique Identifying Codes (UIC) retained by the electronic
    mail system once the user has removed an active note or letter
    from the in-basket.

      The UIC is a system created unique value appended to a note or
letter when it is  created.  The UIC remains with the note or letter
until the note or letter is destroyed (see figure).

      The Inactive Notes & Letters container and the UIC are the key
entities that allow the implementation of the Auto-Elimination
function.  Both entities must be acted on properly by the electronic
mail system in order to function correctly.  The correct functional
implementation is described below.

      The SET function controls a simple switch to determine if
auto-elimination is active or inactive(1.3).  This allows the
individual users to control if auto-elimination is used.

      The WRITE function allows an originator to create a note or
letter.  Auto-elimination is handled as follows:

1.  Originator creates a note or letter.

2.  Originating system assigns a UIC and appends it to the note or
    letter.

3.  The UIC is stored in the originators Inactive Notes &
    Letters(1.2) list.  This prevents the originator receiving
    his/her own note back.

4.  The note or letter is sent to one or more recipients.

      The RECEIVE function accepts notes or letters into the
recipients in-basket.  It handles auto-elimination as follows:

1.  Checks the Auto-Elimination Switch(1.3):  If the switch is OFF,
    then skip to step 4.  If the switch is ON, then go to next step.

2.  Compare the UIC of the received note or letter to the UIC of all
    items in the Active Notes & Letters(1.1) container.  If a match
    is found, then do not add the note or letter to the Active Notes
    & Letters(1.1) container and skip to step 5.  If no match is
    found, then go to next step.

3.  Compare the UIC of the received note or letter to the UICs in the
    Inactive Notes & Letters(1.2) container.  If a match is found,
    then do not add the note o...
