无法从laravel发送电子邮件？

Question

I'm trying to send email using Laravel. I configured mail.php with details of gmail server and used my personal gmail account credentials. It worked fine.

Then i tried to configure mail.php with the Secure SSl/TLS settings that my mail provider has provided me.

I changed host, port, username and password. I also changed encryption to ssl.

But i'm not able to send email. After some loading time, it just shows a blank page. No Error.

here's my config file(have removed doc-blocks):

<?php

return array(    
    'driver' => 'smtp',
    'host' => 'myServerHostAddress',
    'port' => portno,    
    'from' => array('address' => '[e-mail]', 'name' => 'Gambia Dept'),
    'encryption' => 'ssl',
    'username' => 'usernameFromMyServiceProvider',
    'password' => 'myPassword',
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,    
);
