How to use push queues with Laravel 4.2

[donenvy]

Hi all,

I have a current production app using laravel 4.2.
Previously I set the IronMQ configs in config/queue.php and any Mail::queue would use this iron driver from config/queue.php automatically.

So i updated this to package to version 3.* which is showing as compatible with laravel 4.2 and IronMQ v3.

I just sent a mail using Mail::queue and nothing got sent to ironMQ and therefore no mail was sent using ironMQ. Does this package not use the default configs in config/queue.php anymore? And if so how do I get Laravel 4.2 to push mail to ironMQ?
