It is almost ridiculous how easy it is to configure Laravel 4 to send emails via Mandrill .
Open: app/config/mail.php
Change your details to reflect your Mandrill SMTP & API Credentials:
'host' => 'smtp.mandrillapp.com',
'port' => 587,
'username' => '[email protected]',
'password' => 'any valid Mandrill API key'
Save. You’re now sending your transactional emails using Mandrill.
