-Receiving Emails
-----------------
-
-Receiving and parsing emails with Action Mailer can be a rather complex
-endeavor. Before your email reaches your Rails app, you would have had to
-configure your system to somehow forward emails to your app, which needs to be
-listening for that. So, to receive emails in your Rails app you'll need to:
-
-* Implement a `receive` method in your mailer.
-
-* Configure your email server to forward emails from the address(es) you would
-  like your app to receive to `/path/to/app/bin/rails runner
-  'UserMailer.receive(STDIN.read)'`.
-
-Once a method called `receive` is defined in any mailer, Action Mailer will
-parse the raw incoming email into an email object, decode it, instantiate a new
-mailer, and pass the email object to the mailer `receive` instance
-method. Here's an example:
-
-```ruby
-class UserMailer < ApplicationMailer
-  def receive(email)
-    page = Page.find_by(address: email.to.first)
-    page.emails.create(
-      subject: email.subject,
-      body: email.body
-    )
-
-    if email.has_attachments?
-      email.attachments.each do |attachment|
-        page.attachments.create({
-          file: attachment,
-          description: email.subject
-        })
-      end
-    end
-  end
-end
-```
