1. Retry mailer tasks on SMTP failure …

   We are seeing evidence that occasionally the Mandrill SMTP server
   disconnects our mailer, or perhaps that the network between our
   application and Mandrill occasionally drops:

   This commit adds retry logic to the mailer task to ensure that in the
   event of any kind of network or SMTP error, the task is requeued for
   another delivery attempt later.
   
   With the current configuration we will attempt to deliver mail four
   times (i.e. 3 retries) over a period of approximately 20 minutes, using
   an exponential backoff.
