RFC 4469                IMAP CATENATE Extension               April 2006


   Example 2: The following example demonstrates how the CATENATE
   extension can be used to replace edited text in a draft message, as
   well as header fields for the top level message part (e.g., Subject
   has changed).  The previous version of the draft is marked as
   \Deleted.  Note that the server also supports the UIDPLUS extension,
   so the APPENDUID response code is returned in the successful OK
   response to the APPEND command.

   Example 3: The following example demonstrates how the CATENATE
   extension can be used to strip attachments.  Below, a PowerPoint
   attachment was replaced by a small text part explaining that the
   attachment was stripped.

   Example 4: The following example demonstrates a failed APPEND
   command.  The server returns the BADURL response code to indicate
   that one of the provided URLs is invalid.  This example also
   demonstrates how the CATENATE extension can be used to construct a
   digest of several messages.

   Note that the server could have validated the URLs as they were
   received and therefore could have returned the tagged NO response
   with BADURL response-code in place of any continuation request after
   the URL was received.
