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.
