Parsing through email in Ruby using Action Mailer

Question

I retrieve mail using net/pop , but I also need to parse through the email to obtain subject,from address and email body. Any ideas with Action Mailer? I'm supposed to use 3rd party gems.(No,not even Tmail)

require 'rubygems'
require 'net/pop'
require 'pop_ssl'

Net::POP3.enable_ssl(OpenSSL::SSL::VERIFY_NONE)  

def pull_mail
  Net::POP3.start("pop.gmail.com", 995, "uname","pass") do |pop|  

    if pop.mails.empty?  
      puts 'No mails.'  
    else  
      pop.each_mail do |mail|  
      puts mail_header
    end  
  end

end

Cheers!

Basically, you just need to write your email handler, and all the parsing will be done for you behind the scenes:

class MailHandler < ActionMailer::Base
  def receive(email)
    # here you will have an email object and will be able to call methods like
    # email.subject and email.attachments

    puts "from: #{email.from}, subject: '#{email.subject}'"
  end
end

When you get emails using Net::POP3, just hand them off to your handler:

Net::POP3.start(server, port, username, password) do |pop|
  pop.each_mail { |mail| MailHandler.receive(mail.pop) }
end
