title: contact form 7 mail not sending
body: <p>I have used contact form 7 for one of my wordpress sites.
  I have also integrated wp-mail-smtp for sending mail.
  In local site is running properly but When I configure it on server it gives error.
  Problem is though I get success message but it does not send mail to specified email id.
  and when I try to send the test message from smtp, it gives below error</p>
  
  <pre><code>The SMTP debugging output is shown below:
  
  SMTP -&gt; ERROR: Failed to connect to server: Connection timed out (110)
  
  SMTP Error: Could not connect to SMTP host.
  </code></pre>
  
  <p>Can any one specify the problem?</p>
