# frozen_string_literal: true
require "mail"
# 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
