Sends email using Mandrill's JSON API.

Use this adapter to send emails through Mandrill's API. Requires that an API key is set in the config. See Bamboo.MandrillHelper for extra functions that can be used by Bamboo.MandrillAdapter (tagging, merge vars, etc.)

Example config

# In config/config.exs, or config/prod.exs, etc.
config :my_app, MyApp.Mailer,
  adapter: Bamboo.MandrillAdapter,
  api_key: "my_api_key",
  hackney_opts: [
    recv_timeout: :timer.minutes(1)
  ]

# Define a Mailer. Maybe in lib/my_app/mailer.ex
defmodule MyApp.Mailer do
  use Bamboo.Mailer, otp_app: :my_app
end
