  </code></pre>
  
  <p>Since I got no errors, even in <code>laravel.log</code> file I don't know even where to start checking, I have checked for the correct sendmail path though, and it was correct, what am I missing?</p>
  
  <p>I also read that you have to change some things in /etc/hosts I changed it a bit adding "domainexample.com":</p>
  
  <pre><code>127.0.0.1   domainexample.com localhost localhost.localdomain localhost4 localhost4.localdomain4
  ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
  </code></pre>
  
  <p>Is this last thing correct?</p>
