<pre>/*
Before coding, you have to make configurations in Mandrill.
Step 1: Enter Mandrill and register your domain.
Step 2: Configure DNS: DKIM and SPF (This is a good tutorial: https://www.youtube.com/watch?v=uEjP_smeLjU) at https://mandrillapp.com/settings/sending-domains
Step 3: Get a KEY API (https://mandrillapp.com/settings)
Step 4: Code with PHP
Step 5: Good luck! :)
