             ^^^^^^^^^^^^^^^^^^^^^^^^^

Here is the problem;  the server does not return the [TRYCREATE] response.
>From the IMAP4rev1 (RFC 3501) specification:

  Unless it is certain that the destination mailbox can not be created, the
  server MUST send the response code "[TRYCREATE]" as the prefix of the text of
  the tagged NO response.  This gives a hint to the client that it can attempt
  a CREATE command and retry the COPY if the CREATE is successful.

It should return:

  NO [TRYCREATE] Mailbox does not exist

I will work on a way to bypass this problem.

Apart from that imapfilter should not delete the messages if the copy failed;
on which I'm working on.
