Mandrill not able to send mails

Am using laravel 5 and working locally with xampp. In Mail. php

 'driver' => 'smtp',
 'host'=> 'smtp.mandrill.com',
 'port'=> 587,
 'from'=> [
      'address'=> 'myMail@gmail.com',
      'name'=> 'LearningLaravel'
 ],
 'encryption'=> 'tls',
 'username'=> 'myMail@gmail.com',
 'password'=> 'mandrillApiKey',
 'sendmail'=> '/usr/sbin/sendmail -bs',
 'pretend'=> false

In Service.php

 'mandrill'=> [
      'secret'=> 'mandrillApiKey',
      ],
