Mailman

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.

There is also a great Getting Started Guide written by Dan Sowter.

Installation

gem install mailman

Tested on all Ruby versions with Travis CI.

This project was sponsored by the Ruby Summer of Code, and my mentor was Steven Soroka.
