Mailbox already exists.

[Shawn Fisher]

I was running into this error with the latest git pull of offlineimap
on arch linux:

ERROR: Exceptions occurred during the run!
 ERROR: Creating folder Journal on repository main-local
  Folder 'sent'[main-remote] could not be created. Server responded:
('NO', ['Mailbox already exists.'])

Traceback:
  File "/usr/lib/python2.7/site-packages/offlineimap/repository/Base.py",

    src_repo.makefolder(newsrc_name)
  File "/usr/lib/python2.7/site-packages/offlineimap/repository/IMAP.py",
line 336, in makefolder
    OfflineImapError.ERROR.FOLDER)

    OfflineImapError.ERROR.FOLDER)

A simple hack to get myself around this was to change the logic for
the makefolder (IMAP.py) function from:

. . .
            if result[0] != 'OK':
                raise OfflineImapError("Folder '%s'[%s] could not be created. "
. . .

to
. . .
            if result[0] != 'OK' and 'Mailbox already exists.' not in result[1]:
               raise OfflineImapError("Folder '%s'[%s] could not be created. "
. . .

Please don't flame me, I just needed a quick solution to the issue.  I
hope it helps you find the error and a proper fix.

If you need more info, let me know,
