title: zabbix not sending email to gmail
body: <p>I have been busy trying this for hours now. 
  What am I missing here? Does anybody have any clues?</p>
  
  <p>I am trying to send notifications emails with zabbix to gmail. 
  Have set up the email account as follow.</p>
  
  <pre><code>Type: 'Email'
  SMTP Server: 'smtp.gmail.com'
  SMTP server Port: '25'
  SMTP HELO: 'gmail.com'
  SMTP email: '[username]@gmail.com'
  Connection security 'none'
  Authentication: 'username and password'
  Username '[username]' // without @gmail.com
  Password '[password]'
  Enabled 'checked'
  </code></pre>
  
  <p>I have also created an action and a trigger. 
  This works perfect. </p>
  
  <p>If I look at reports and audits I see the following;</p>

  <p>It seems to me that the function is working like it should, but I don't receive any emails. Am I doing something wrong here? </p>
  
  <p>I also set the non-secure apps options on in Gmail and I have opened port 25 on the server.</p>
  
  <p>Help is highly appreciated.
  As always Thank you!</p>
