Your IMAP server is broken.  IMP is issuing:

10 UID COPY 1:50 "INBOX.Sent-jan-2012"

Your server is responding with

10 BAD The folder could not be found.

This is incorrect.  If INBOX.Sent-jan-2012 can be created, the  
response MUST be:

10 NO [TRYCREATE] The folder could not be found.

Your server is 1) incorrectly returning BAD and 2) not returning the  
TRYCREATE response code.

 From RFC 3501 [6.4.7]:

       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.

Since I've been yelled at multiple times over on the imap list for  
trying to support broken IMAP server installations, I'm hesitant to  
try to workaround this issue in code.
