Configuring ingress involves 1. Setting up credentials 2. Endpoint information for the chosen email service.
Some supported ingresses are:
<ul>
<li>Exim
</li>
<li>Mailgun
</li>
<li>Mandrill
</li>
<li>Postfix
</li>
<li>Postmark
</li>
<li>Qmail
</li>
</ul>
Mandrill Ingress setup:
Use <code>rails credentials:edit</code> to add your API key to your application's encrypted credentials under <code>action_mailbox.mandrill_api_key</code>, where Action Mailbox will automatically find it:
<pre><code class="lang-ruby">action_mailbox:
 mandrill_api_key: ...
</code></pre>
Alternatively, provide API key in the <code>MANDRILL_INGRESS_API_KEY</code> environment variable.
Tell Action Mailbox to accept emails from Mandrill:
<pre><code class="lang-ruby"># config/environments/production.rb
config.action_mailbox.ingress = :mandrill
</code></pre>
