python login 163 mail server

问题:

When I use this script to login the 163 mail server,there is something wrong! My python env is python 2.7.8 Please help me!

import imaplib

def open_connect(verbose=False):
    host = 'imap.163.com'
    port = 993
    if verbose:print 'Connecting to',host
    connection = imaplib.IMAP4_SSL(host)
    username = '[e-mail]'
    passwd = 'aaannnmmm'
    if verbose:print 'Logging in as',username
    try:
        connection.login(username,passwd)
    except Exception as err:
        print 'ERROR:', err

    return connection

c = open_connect()

try:
    tye,data = c.select('INBOX')
    print tye,data
    num_msgs=int(data[0])
    print 'There are %d messages in INBOX' % num_msgs
finally:
    c.close()
    c.logout()

NO ['SELECT The login is not safe! Please update your mail client: http://mail.163.com/dashi']
Traceback (most recent call last):
  File "imap_select.py", line 26, in <module>
    c.close()
  File "/usr/lib/python2.7/imaplib.py", line 382, in close
    typ, dat = self._simple_command('CLOSE')
  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 825, in _command
    ', '.join(Commands[name])))
imaplib.error: command CLOSE illegal in state AUTH, only allowed in states SELECTED

===== And then the 163 mail server send me a mail,about this:

该行为存在以下安全隐患：
1） 邮件客户端未经有效识别，不能有效保证帐户安全性，存在帐号密码泄漏的风险；
2） 数据传输安全性低，存在数据泄漏风险。

In English is :

1) mail client not a security client 
2) data streaming is notsecruity

Thanks a lot. This is the debug info . I think that I must a have a TLS1.2 version conection.

After netease blocking your own client, they will send you an email named 网易邮箱提醒：阻止了一次不安全的收信请求 by [e-mail].

On the bottom of the email, they provided a link to the configure page:

http://config.mail.163.com/settings/imap/index.jsp?uid=[e-mail]

Replace YOUR_EMAIL_NAME by yourself.

Netease is promoting their new mobile email app "邮箱大师", and they currently blocked any imap client other than their offical clients and several popular clients such as thunderbird, foxmail. I don't know how do they identified the client. Anyway, may it's time for you to switch to other email service provider. At least QQ mail works well.

Please show us the debug output produced by your IMAP library. It seems that the server administrators have configured their server to always reject LOGIN even though you are on a secure SSL connection. That's an interesting choice, but some providers do that. Talk to their support about how you are supposed to connect to their service.
