+module ActionMailbox
+  # The `InboundEmail` is an Active Record that keeps a reference to the raw email stored in Active Storage
+  # and tracks the status of processing. By default, incoming emails will go through the following lifecycle:
+  #
+  # * Pending: Just received by one of the ingress controllers and scheduled for routing.
+  # * Processing: During active processing, while a specific mailbox is running its #process method.
+  # * Delivered: Successfully processed by the specific mailbox.
+  # * Failed: An exception was raised during the specific mailbox's execution of the `#process` method.
+  # * Bounced: Rejected processing by the specific mailbox and bounced to sender.
+  #
+  # Once the `InboundEmail` has reached the status of being either `delivered`, `failed`, or `bounced`,
+  # it'll count as having been `#processed?`. Once processed, the `InboundEmail` will be scheduled for
+  # automatic incineration at a later point.
+  #
+  # When working with an `InboundEmail`, you'll usually interact with the parsed version of the source,
+  # which is available as a `Mail` object from `#mail`. But you can also access the raw source directly
+  # using the `#source` method.
+  #
+  # Examples:
+  #
+  #   inbound_email.mail.from # => 'david@loudthinking.com'
+  #   inbound_email.source # Returns the full rfc822 source of the email as text
