[Mailman-Users] smtp error - [Errno 111] Connection refused - when trying to install MM 3.0

[Danci Emanuel]

Hello everyone!

I am working on configuring MM 3.0 on my machine using these
instructions - http://bazaar.launchpad.net/~mailman-coders/mailman/3.0/view/head:/src/mailman/docs/WebUIin5.rst 
and when I run the bin/test command (line 34), when running the 
'mailman.testing.layers.SMTPLayer tests' I get the following 
error: 'error: [Errno 111] Connection refused'. 

This is the complete error message: 
 Running mailman.testing.layers.SMTPLayer tests:
  Tear down mailman.testing.layers.LMTPLayer in 0.009 seconds.
  Set up mailman.testing.layers.SMTPLayer Traceback (most recent call last):

    self.sock = self._get_socket(host, port, self.timeout)
  File "/usr/lib/python2.6/smtplib.py", line 273, in _get_socket
    return socket.create_connection((port, host), timeout)
  File "/usr/lib/python2.6/socket.py", line 514, in create_connection
    raise error, msg
error: [Errno 111] Connection refused

I know that has to do something with the smtp server, 
but I do not know exactly how to solve it, so any feedback
is welcome!

Thanks in advance for your help!
