Hello, Looks like imaplib is case sensitive, even though the IMAP protocol isn't:
(1) Except as noted otherwise, all alphabetic characters are case-insensitive. The use of upper or lower case characters to define token strings is for editorial clarity only. Implementations MUST accept these strings in a case-insensitive fashion. http://tools.ietf.org/html/rfc3501#section-9 For example: [Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) ] [imaplib 2.58] import imaplib M = imaplib.IMAP4( 'localhost', 1143 ) M.login( 'user', 'password' ) M.select() typ, data = M.search(None, 'ALL') for num in data[0].split(): typ, data = M.fetch(num, '(ENVELOPE)') print 'Message %s\n%s\n' % (num, data[0][1]) M.close() M.logout() Traceback (most recent call last): File "Test.py", line 3, in <module> M = imaplib.IMAP4( 'localhost', 1143 ) File "python2.6/imaplib.py", line 184, in __init__ self.welcome = self._get_response() File "python2.6/imaplib.py", line 935, in _get_response raise self.abort("unexpected response: '%s'" % resp) imaplib.abort: unexpected response: '* ok imap4rev1' Note the 'ok' tag in lower case. -- http://mail.python.org/mailman/listinfo/python-list
