Fix my plugin so it sends email through Mandrill and not Wordpress default

Hello, I am a WordPress plugin developer and happen to have a plugin in the WordPress plugin repository which redirects emails - so I know a fair bit about emails in WordPress. I dare say that the Freelancer you've hired has not used the WordPress emailing functionality. This should be a quick and easy fix, I hope I can help. Thanks for your consideration.
