Sorry to be unhelpful in describing the issue. The password and username
 credentials are all correct. I am using BuildBot MailNotifier to send 
an email each time a build has taken place:<br><br><pre><code><span>                 </span><span>from</span><span> buildbot</span><span>.</span><span>status </span><span>import</span><span> mail<br>

<br></span></code></pre><br>I am a new user to twisted and am unsure of what it would be helpful to show. The traceback I have shown is from the twistd.log. If I can&#39;t expect it to work with some other authentication method then how can the problem be resolved?<br>

IIRC the Twisted SMTP stuff has support for handling auth errors and<br>
trying other methods; it should &quot;just work&quot;.<br></blockquote></div><div><br>The code is a bit convoluted, so I can&#39;t be sure without more time than I want to spend on it, but I wouldn&#39;t expect it to try more than one auth method. If you send your username and password with CRAM-MD5 and got an error, why would you expect it to work with some other authentication method? It&#39;s still the same credentials.<br>
