title: Swiftmailer doesn't work in localhost?
body: <p>I am using symfony 3.0 Version:
  <strong>Config.yml</strong></p>
  
  <pre><code># Swiftmailer Configuration
  swiftmailer:
      transport: "%mailer_transport%"
      host:      "%mailer_host%"
      username:  "%mailer_user%"
      password:  "%mailer_password%"
      port:      %mailer_port%
      spool:     { type: memory }
  </code></pre>
  
  <p><strong>Parameters.yml</strong></p>
  
  <pre><code>mailer_transport: smtp
      mailer_host: localhost
      mailer_port: 25
      mailer_user: pankaj@acb.com
      mailer_password: abc123
  </code></pre>
  
  <p>I run the following command for sending the mail:</p>
  
  <pre><code>php Console Swiftmailer:spool:send 
  </code></pre>
  
  <p>processing default mailer .... 0 emails sent</p>
  
  <pre><code>php Console Swiftmailer:email:send
  </code></pre>
  
  <p>sent 1 emails</p>
  
  <p>app.ERROR: Exception occurred while flushing email queue:
  Connection could not be established with host 127.0.0.1 [An attempt was made to
  access a socket in a way forbidden by its access permissions.  #10013]</p>
  
  <p>I did also try via code:</p>
  
  <pre><code>$message = \Swift_Message::newInstance()
                      -&gt;setSubject('Hello Email')
                      -&gt;setFrom('pankaj@acb.com')
                      -&gt;setTo('ashish@acb.com')
                      -&gt;setBody('good jb');            
              $this-&gt;get('mailer')-&gt;send($message);
  </code></pre>
  
  <p>But i did not get any exception/error/message.</p>
  
  <p>Anyone can suggest me what can i do ? Thanks</p>
