Aquípongo un receta rápida de como enviar correos a través de Gmail.

Primero en el directorio /lib creamos un fichero llamado smtp_tls.rb que contenga:

require 'openssl'
require 'net/smtp'

Net::SMTP.class_eval do
  private
  def do_start(helodomain, user, secret, authtype)
    raise IOError, 'SMTP session already started' if @started
    check_auth_args user, secret, authtype if user or secret

    sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
    @socket = Net::InternetMessageIO.new(sock)
    @socket.read_timeout = 60 #@read_timeout

    check_response(critical { recv_response() })
    do_helo(helodomain)

    raise 'openssl library not installed' unless defined?(OpenSSL)
    starttls
    ssl = OpenSSL::SSL::SSLSocket.new(sock)
    ssl.sync_close = true
    ssl.connect
    @socket = Net::InternetMessageIO.new(ssl)
    @socket.read_timeout = 60 #@read_timeout
    do_helo(helodomain)

    authenticate user, secret, authtype if user
    @started = true
  ensure
    unless @started
      # authentication failed, cancel connection.
      @socket.close if not @started and @socket and not @socket.closed?
      @socket = nil
    end
  end

  def do_helo(helodomain)
    begin
      if @esmtp
        ehlo helodomain
      else
        helo helodomain
      end
    rescue Net::ProtocolError
      if @esmtp
        @esmtp = false
        @error_occured = false
        retry
      end
      raise
    end
  end

  def starttls
    getok('STARTTLS')
  end

  def quit
    begin
      getok('QUIT')
    rescue EOFError
    end
  end
end

Al final del fichero config/environment.rb añadimos:

require 'lib/smtp_tls'

yaml_contents = File.open("#{RAILS_ROOT}/config/mailer.yml") 
mailer_options = YAML.load(yaml_contents) 
ActionMailer::Base.smtp_settings = mailer_options 

Y por último la configuración de la cuenta en config/mailer.yml:

:address: "smtp.gmail.com" 
:port: 587 
:domain: "tudominio.com" 
:user_name: "usuario@gmail.com" 
:password: "contraseña" 
:authentication: :plain
