SSL options for 'Zend\Mail\Transport\Smtp' in Zend Framework 2

Is it possible to set these SSL options:

    'allow_self_signed' => true,
    'verify_peer' => false,
    'verify_peer_name' => false

for ‘Zend\Mail\Transport\Smtp’ in Zend Framework 2 app? If it is possible, please let me know how to do it. I am trying to send emails on my local MS IIS server via TLS and I get the error ‘Unable to connect via TLS’. I use PHP 5.6.
