Use of Message Store as a Repository for Deferred Delivery Mail

      This article describes a method for using an X.400
message store (MS) as a repository for mail items that have been sent
with a deferred delivery time.

      X.400 is the international standard for electronic mail.  This
standard provides for the deferred delivery of a mail item to a user.
The standard also provides for the cancellation of deferred delivery
mail before it has been delivered.  However, there is no method
defined for the retrieval of a mail item when its deferred delivery
is cancelled.

      When a User Agent (UA) submits a mail item to the Message
Handling System (MHS) with a deferred delivery time, a copy will be
kept at the MS.  If the user wishes to cancel the delivery before the
deferred delivery time, the MS can send the cancel request to the MHS
and return the copy of the mail item back to the UA.

      If the user does not cancel the deferred delivery, the MS can
discard the mail item after the deferred delivery time has been
reached.

      This solution offers several advantages.  The first is that it
is conformant to X.400.  An additional advantage is that it provides
the added function of allowing a user to retrieve deferred delivery
mail items.  It also provides a mechanism for UAs that have no local
storage to have a deferred delivery mail item stored for retrieval on
a cancel since these UAs would be unable to keep a copy.
