<p>Currently STARTTLS check does not work with -e if there's text like '220 hostname ESMTP*'. This is caused by SMTP answer from host. </p>

<p>Postfix answer: <strong>220 2.0.0 Ready to start TLS</strong><br>
Exchange 2010: <strong>220 2.0.0 SMTP server ready</strong></p>

<p>This fix introduces a constant for '220 2.0.0' which is used to check if TLS connection is ok</p>
