Rails ApplicationMailbox not routing on staging - ActionMailbox

Question

So I added a mailbox to my app using Rail's ActionMailbox. It's set the following way:

A small email server: basically a docker image running Postfix behind a rails-api application with ActionMailbox set-up. Very similar to this: https://github.com/Loumaris/action-mailbox-docker-postfix-relay

The main-app where the internal routing and email processing is set:

class ApplicationMailbox < ActionMailbox::Base
  routing :all => :imports
end

class ImportsMailbox < ApplicationMailbox
  def process
    ...
  end
end

Now, both apps are deployed in the same cluster (using kubernetes). Each on it's own container. ActionMailbox's config for relay SMTP services is set with:

bin/rails action_mailbox:ingress:postfix URL=https://main-app.com/rails/action_mailbox/relay/inbound_emails INGRESS_PASSWORD=...

The first part works well, the email server pipes emails to the main-app and instances of InboundEmail objects are created there. The problem is the internal routing (inside main-app) never takes place. Emails are never redirected to ImportsMailbox to be processed:

class ApplicationMailbox < ActionMailbox::Base
   routing :all => :imports # this routing never happens
end

Not only this works fine locally, but if I run the main-app from my computer, set a public ngrok host and make email server point at it:

bin/rails action_mailbox:ingress:postfix URL=https://ngrok-host-running-my-local-app.com/rails/action_mailbox/relay/inbound_emails INGRESS_PASSWORD=...

it also works. So the problem might be somewhere within staging env setting.

Some info regarding logs. This is when main-app gets an email:

And right after we see these warnings:
