title: Laravel with Postfix
body: <p>I was using gsuite to send mail from laravel, config on .env was:</p>
  
  <pre><code> MAIL_DRIVER=smtp
   MAIL_HOST=smtp.gmail.com
   MAIL_PORT=465
   MAIL_USERNAME=account@gmail.com
   MAIL_PASSWORD=password123
   MAIL_ENCRYPTION=ssl
  </code></pre>
  
  <p>It is working ok, but now i installed postfix as a send-only to send newsletters and tested via command line like this:</p>
  
  <pre><code>echo "Teste message" | mail -s "Title Message" any@email.com
  </code></pre>
  
  <p>And it worked ok, but i cant figure on how to use it on laravel, what should be the configuration? I tried this:</p>
  
  <pre><code> MAIL_DRIVER=smtp
   MAIL_HOST=localhost
   MAIL_PORT=25
   MAIL_USERNAME=null
   MAIL_PASSWORD=null
   MAIL_ENCRYPTION=null
  </code></pre>
  
  <p>But it return:</p>
  
  <pre><code>Swift_TransportException
  Expected response code 220 but got code "", with message ""
  </code></pre>
