Mailman is an incoming mail processing microframework (with POP3 and Maildir support), that works with Rails "out of the box".

require 'mailman'
Mailman::Application.run do
  to 'ticket-%id%@example.org' do

    Ticket.find(params[:id]).add_reply(message)
  end
end

See the User Guide for more information.

Tested on Ruby 2.1, 2.0, 1.9.3, JRuby, and Rubinius.

In order to use this gem with ruby versions older then 2.0.0, you have to restrict the maildir gem to the latest supported version in your Gemfile:

gem 'maildir', '< 2.1.0'
