Iteration K1: Receiving Support Emails with Action Mailbox

Configuring Rails to receive emails requires three steps: initially setting up Action Mailbox, setting up Active Storage to hold the raw emails we receive, and implementing a mailbox, which is like a controller that handles incoming emails.

Setting up Action Mailbox

To set up Action Mailbox in our app, we’ll run a Rake task that will create some configuration files, a base mailbox class we’ll inherit from, and some database tables that Rails will use to store information about incoming emails. Let’s run the Rake task:

> bin/rails action_mailbox:install
Copying application_mailbox.rb to app/mailboxes
      create  app/mailboxes/application_mailbox.rb
