Action Mailbox

Action Mailbox routes incoming emails to controller-like mailboxes for
processing in Rails.  It ships with ingresses for Mailgun, Mandrill,
Postmark, and SendGrid.  You can also handle inbound mails directly via the
built-in Exim, Postfix, and Qmail ingresses.

The inbound emails are turned into `InboundEmail` records using Active
Record and feature lifecycle tracking, storage of the original email on
cloud storage via Active Storage, and responsible data handling with
on-by-default incineration.

These inbound emails are routed asynchronously using Active Job to one or
several dedicated mailboxes, which are capable of interacting directly with
the rest of your domain model.
