ruby-on-rails - 如何使诸如“script/mailman_server”之类的脚本适用于 Rails 应用程序中的多个用户

Question

我有一个 Rails 应用程序，它使用 mailman gem（链接）来收集入站 pop3 邮件并处理它们。这一切都很好，但现在我希望有多个用户注册并从他们的 pop3 配置中接收邮件。Mailman 在“script/mailman_server”中运行，我不熟悉如何使脚本（运行自己的进程）为多个用户工作。任何人都可以就该主题启发我或链接到涉及该主题的资源吗？

这是我现在的代码

# script/mailman_server

#!/usr/bin/env ruby
require "rubygems"
require "bundler/setup"
require "mailman"

Mailman.config.pop3 = {
  :username => 'some_name@some_email.com',
  :password => 'some_password',
  :server   => 'pop.gmail.com',
  :port     => 995,
  :ssl      => true
}

Mailman::Application.run do
  default do
    Email.receive_mail(message)
  end
end


# app/models/email.rb

class Email
  include Mongoid::Document
  include Mongoid::Timestamps

  field :from, type: String
  field :subject, type: String
  field :body, type: String

  belongs_to :customer, :inverse_of => :emails

  def self.receive_mail(message)
    email = Email.create!(subject: message.subject, body: message.body.decoded, from: message.from.first)
  end
end
