Since most of the ingress controllers receive raw MIME data in POST body,
it is impossible to guaratee that these are in UTF-8 as email comes in all
possible encodings.
This patch disables force transcoding to UTF-8 by ActionController params
processing for params that contain RAW MIME email bodies.
Fix#46297
Prior to this commit, when adding attachments to an inbound email
through the conductor, the log would warn of an unpermitted parameter
with the message:
> Unpermitted parameter: :attachments. Context: { }
Also, if an application had the setting:
config.action_controller.action_on_unpermitted_parameters = :raise
it would raise an error, because the attachments are not a permitted
parameter.
This commit also sets `action_on_unpermitted_parameters` to `:raise`
for the action mailbox test suite, so that tests are run in most
restrictive setting available, to prevent future unpermitted parameters
from being passed by conductor actions.

This is imperfect in situations when a separation
between regular files (such as uploads) and emails
is necessary (for the purposes of regulatory compliance,
proper compartmentalization, etc.)
Solution: allow configuring ActionMailbox's storage service
Sendgrid, like Mailgun, only passes BCC recipients as a parameter in the original JSON payload.
This PR adds code to prepend the recipients from the Sendgrid payload to the raw_email under the X-Original-To header.

Mandrill's Inbound API checks to see if a URL exists before it creates
the webhook. It sends a HEAD request, to which we now return a 200 OK
response to indicate that the route exists.
Now we can generate inbound API calls with ease on Mandrill, without
having to shuffle around tokens in production.
Fixes#37609.
* Add a way to deliver inbound emails by source
Great for testing when you get an eml file and can just paste it in.
* Test updates
* Fix tests
* Fix spacing
Expose the Mailgun SMTP recipient to Action Mailbox as X-Original-To, like Postfix.
Allows handling BCCed recipients who aren't listed in To/CC fields.
Allow passing a block to the create_inbound_email_from_mail and
receive_inbound_email_from_mail test helper methods.
When you wanted to test a multipart email -- for example, an email that
has both a plaintext part and an HTML part -- there wasn't a way to
easily build one without a pre-made fixture. By allowing you to pass a
block to these methods, we unlock the power of Mail.new to easily
create a variety of emails, from multi-part emails, to emails with
attachments, and beyond.
