    <p>Iko,</p>
    <p>You will find the answers at the link of PHP Mailer
      troubleshooting on GitHub:<br>
    </p>
    <p><a class="moz-txt-link-freetext" href="https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting">https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting</a></p>
    <p>Even the DNS issue is listed there. Also you will find the proper
      port settings examples, both of tls and ssl.<br>
      The vtiger requires SMTP host in the format:
      ssl://smtp.example.com:465 or tls://smt.example.com:587 and the
      PHP Mailer will it parse properly.</p>
    <p>The DNS issue can be tested by the <a class="moz-txt-link-freetext" href="https://mxtoolbox.com/">https://mxtoolbox.com/</a> <br>
    </p>
    <p>And this is the very important part of the troubleshooting guide
      from the GitHub<br>
    </p>
    <p>If you check all circumstances and it's still not working!<br>
      <br>
      <i>If any of the above checks fail, PHPMailer will not work
        either, and usually there's nothing that PHPMailer can do about
        it. <font color="#cc0000"><b>So go fix your network, then try
            again.</b></font> If you are not in control of your own
        firewall or DNS, you probably need to raise a support ticket
        with your ISP to fix this (it's very common for them to block or
        divert port 25 outbound). <font color="#cc0000"><b>If they
            won't fix it, you need to replace your ISP</b></font>. PS:
        BlueHost doesn't support smtp.gmail.com, they want you to use
        their smtp server. The work around would be to use email
        associated with BlueHost and their host address Or send using
        mail() function in this case.</i><br>
    </p>
    <p>Note: because of these reasons I had just moved one of my clients
      from GoDaddy to a virtual private server hosted at InMotion
      Hosting.<br>
