Problem sending emails in Plone5.0b2

Hi folks,

I'm testing Plone5.0b2. I configured the email in the "mail settings"
form. It works. I received the email when I press the "Save and send
test e-mail". Then I went to "users and groups" and I request a new
password for an user that I have previously created. The page shows an
info box that the email was sent. However, I do not receive any emails
and the following error is registered in the log file:

2015-07-11T14:44:00 ERROR MailDataManager Connection unexpectedly closed
Traceback (most recent call last):
  File

  File

  File "/usr/lib/python2.7/smtplib.py", line 745, in sendmail
    self.rset()
  File "/usr/lib/python2.7/smtplib.py", line 469, in rset
    return self.docmd("rset")
  File "/usr/lib/python2.7/smtplib.py", line 394, in docmd
    return self.getreply()
  File "/usr/lib/python2.7/smtplib.py", line 368, in getreply
    raise SMTPServerDisconnected("Connection unexpectedly closed")
SMTPServerDisconnected: Connection unexpectedly closed

By the way, I'm not sure about where to post this if this where an
issue. I see several issue trackers related to Plone.

Cheers,
Daniel
