1.  Introduction

   Users are not always ready, willing, or able to read and respond to
   email messages at the time of their arrival.  Sometimes it is
   desirable to have messages appear in a mailbox at a more convenient
   time for the user to act upon them.

   This document defines an extension to the Sieve language [RFC5228]
   that enables scripts to postpone the delivery of a message into a
   target mailbox until a later point in time.

2.  Conventions Used in This Document

   Conventions for notations are as in Section 1.1 of [RFC5228],
   including use of the "Usage:" label for the definition of action and
   tagged arguments syntax.
