title: Laravel mail will not receive by gmail users
body: <p>When I send email by laravel <code>non-gmail</code> accounts <strong>will receive</strong> emails but <code>Gmail accounts</code> <strong>will not</strong>, does anyone here faced such problem before? <strong>any idea what causes that?</strong></p>
  <blockquote>
  <p>As my emails are receiving with half of the users I don't think the issue is my code but just in case i share it here as well.</p>
