function template_preprocess_mandrill_message in Mandrill 7.2
A preprocess function for theme('mandrill_message').
The $variables array initially contains the following arguments:
- $recipient: The recipient of the message
- $key: The mailkey associated with the message
- $subject: The message subject
- $body: The message body
@todo maybe replace call to mailsystem_get_mail_theme() with mandrill-specific setting?
