imaplib problem

[levann]

Hi there

I am trying to remake python email bot, which will satisfy my needs.
I have used code from this source

I had some errors, and I was able to resolve them, but now I am stacked.

I am getting this error

Error:
Traceback (most recent call last):
  File "/usr/lib64/python3.6/imaplib.py", line 1019, in _command_complete
    typ, data = self._get_tagged_response(tag)
  File "/usr/lib64/python3.6/imaplib.py", line 1131, in _get_tagged_response
    self._check_bye()
  File "/usr/lib64/python3.6/imaplib.py", line 934, in _check_bye
    raise self.abort(bye[-1].decode(self._encoding, 'replace'))
imaplib.abort: mail.nls.ge Zimbra IMAP4rev1 server closing connection

During handling of the above exception, another exception occurred:

    raise self.abort('command: %s => %s' % (name, val))
imaplib.abort: command: SEARCH => mail.nls.ge Zimbra IMAP4rev1 server closing connection

Any ideas? :)
