This is a feature request to implement the IMAP CATENATE extension - http://ietf.org/rfc/rfc4469.txt

Abstract

   The CATENATE extension to the Internet Message Access Protocol (IMAP)
   extends the APPEND command to allow clients to create messages on the
   IMAP server that may contain a combination of new data along with
   parts of (or entire) messages already on the server.  Using this
   extension, the client can catenate parts of an already existing
   message onto a new message without having to first download the data
   and then upload it back to the server".

A very useful extension currently implemented by the Cyrus server and Polymer http://dave.cridland.net/acap/polymer.html , and already in use by Fastmail (though it is not advertised - notice the two different capability responses) :
