title: fsockopen error after upgrading to php 7
body: <p>I run codeigniter3.03 on digital ocean nginx and  php 7. When I try to send an email I get this error:</p>
  
  <p>Code:</p>
  
  <blockquote>
    <p>Severity: Warning
    Message: fsockopen(): unable to connect to ssl://smtp.googlemail.com:465 (Connection timed out)
    Filename: libraries/Email.php
    Line Number: 1986</p>
  </blockquote>
  
  <p>My email setup is </p>
  
  <pre><code>$config['useragent'] = 'CodeIgniter';
  $config['protocol'] = 'smtp';
  //$config['mailpath'] = '/usr/sbin/sendmail';
  $config['smtp_host'] = 'ssl://smtp.googlemail.com';
  $config['smtp_user'] = 'xxxxxx@gmail.com';
  $config['smtp_pass'] = 'xxxxxxxxxxxx';
  $config['smtp_port'] = 465; 
  $config['smtp_timeout'] = 5;
  $config['wordwrap'] = TRUE;
  $config['wrapchars'] = 76;
  $config['mailtype'] = 'html';
  $config['charset'] = 'utf-8';
  $config['validate'] = FALSE;
  $config['priority'] = 3;
  $config['crlf'] = "\r\n";
  $config['newline'] = "\r\n";
  $config['bcc_batch_mode'] = FALSE;
  $config['bcc_batch_size'] = 200;
  </code></pre>
  
  <p>This version runs flawlessly in the same config under php 5.x. </p>
  
  <p>in php.ini i have </p>
  
  <pre><code> extension=php_openssl.dll
  </code></pre>
  
  <p>enabled.</p>
  
  <p>I could not get any hint anywhere why this should not work in php7. Can anybody give me a hint what to check or what the cause of this error could be.</p>
