title: reading gmail is failing with IMAP
body: <p>I am running a cron job which executes the python script for reading gmail (2 min interval). I have used imaplib for reading the new mails. This was working fine until yesterday. Suddenly its throwing below error</p>
  
  <blockquote>
    <p>imaplib.error: [AUTHENTICATIONFAILED] Invalid credentials (Failure)</p>
  </blockquote>
  
  <p>and sometimes i am getting the below error</p>
  
  <blockquote>
    <p>raise self.abort(bye[-1]) imaplib.abort: [UNAVAILABLE] Temporary System Error </p>
  </blockquote>
  
  <p>When i run the same script on a different machine. Its working fine. I am assuming that the host has been blacklisted or something like that. </p>
  
  <p>What are my options ? </p>
  
  <p>I cant generate the Credentials (Gmail API) as this is under company domain account.</p>
