title: AttributeError: 'module' object has no attribute 'message_from_bytes'
body: <p>I am trying to read a mail , which has html content in it. I am using message_from_bytes to read the data from mail.</p>
  
  <pre><code>def ParseEmail(email_user,email_pass,host,port,pdf):
      message_list = []
      mail = imaplib.IMAP4_SSL(host, port)
      mail.login(email_user, email_pass)
      mail.select()
      typ, data = mail.search(None, 'unseen')
      mail_ids = data[0]
      id_list = mail_ids.split()
      for num in id_list:
          typ, data = mail.fetch(num, '(RFC822)')
          raw = email.message_from_bytes(data[0][1])
          raw_email = data[0][1]
          raw_email_string = raw_email.decode('utf-8')
          email_message = email.message_from_string(raw_email_string)
          soup = BeautifulSoup(get_body(raw))
          content = soup.get_text('\n').replace('\xa0:\n\xa0\n', ' ')
          message_list.append(content)
  </code></pre>
  
  <p>the code compiles and runs without any error. when checked with IPython console, the message_list array is also printed. but, when I call this through driver functions I am getting error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "parseemail.py", line 395, in &lt;module&gt;
      main()
    File "/Users/test/dev/Email/parseemail.py", line 384, in main
      pe = ParseEmail(email_user, email_pass, host, port,pdf)
    File "/Users/test/dev/Email/parseemail.py", line 320, in ParseEmail
      raw = email.message_from_bytes(data[0][1])
  AttributeError: 'module' object has no attribute 'message_from_bytes'
  </code></pre>
  
  <p>what could br the possible error? (All the packages are installed and tested).</p>
