1.  Introduction

   The Sieve Email Filtering Language [RFC5228] provides a number of
   action commands, some of which can generate additional messages on
   behalf of the user.  Two such commands are defined by the Vacation
   [RFC5230] and Notify [RFC5435] extensions.  It is sometimes desirable
   to have an archive of the messages generated by these commands.

   This extension defines a new optional tagged argument ":fcc" to
   action commands which generate additional messages to allow a copy of
   the generated message to be filed into a target mailbox.

   The capability string associated with this extension is "fcc".
