# a rake task
namespace :kc_mail do
  desc "Checking mails"
  task :postman => :environment do
    a_pm = Postman.new
    a_pm.save
    a_pm.walk

#######
the Postman walk method actually queue mails :
Delayed::Job.enqueue MailJob.new(message_id)

##### mail_job.rb

class MailJob < Struct.new(:message_id)
  def perform
   something
  end
