title: python and sll/Exchange 2007: No suitable authentication method found
body: <p>I'm trying to send emails from a python script with smtplib, and it works with no problems with smtp through Exchange 2003, but with Exchange 2007 shows:</p>
  
  <pre><code>SMTPException: No suitable authentication method found.
  </code></pre>
  
  <p>Python code is the same in both cases (except server and login information of course).</p>
  
  <p>I'm passing username and password in a script in plain text, and looks like Exchange 2007 is not configured to work with AUTH_PLAIN = "PLAIN" (line 545 of smtplib.py), and I don't know where to disable ssl there.</p>
  
  <p>Would appreciate any ideas.</p>
