[New-bugs-announce] [issue18153] python imaplib - error 'unexpected repsonse'

[tahnoon pasha]

New submission from tahnoon pasha:

Hi I've suddenly encountered an error using imaplib on some code that worked fine before.

    import imaplib
    m = imaplib.IMAP4('myserver','port')
    m.login(r'username','password')
    m.select()

gives me the error 

    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "/usr/lib/python2.7/imaplib.py", line 649, in select
        typ, dat = self._simple_command(name, mailbox)
      File "/usr/lib/python2.7/imaplib.py", line 1070, in _simple_command
        return self._command_complete(name, self._command(name, *args))
      File "/usr/lib/python2.7/imaplib.py", line 899, in _command_complete
        raise self.abort('command: %s => %s' % (name, val))
    imaplib.abort: command: SELECT => unexpected response: '*  1520 EXISTS'

I'm not sure what it means. Emails are otherwise coming through fine, and I'm using davmail as a server.

The program in its entirety saves attachments with a certain name in a specific folder. 

I've stepped through it and its definitely the `m.select()` that is where its falling over.

This same program worked absolutely fine until recently.

What am I doing wrong, and how do I fix it?

I understand that this seems to be occurring because of the extra spaces in the final RETURN from a query on stack overflow

http://stackoverflow.com/questions/16911238/python-imaplib-error-unexpected-repsonse

and it was suggested I file an issue report.

I'm using Davmail as the server on Ubuntu 13.04 and the server works fine with Thunderbird, Fetchmail and Evolution 

My first attempt at filing an issue so apologies if I've done something wrong.
