Tiny resque mail worker setup that removes Rail's stupid dependencies so we can delay messages without the whole rails env. (used w mongo fork)

AnyMailer.rb

require 'zlib'

class AnyMailer < ActionMailer::Base


  def enqueue(method, *args)
    message = self.send(method, *args)
    Resque.enqueue(MailWorker, message: compressed_msg(message))
  end

  # Could easily be changed to not use BSON
  def compressed_msg(msg)
    BSON::Binary.new(Zlib::Deflate.deflate(msg.to_yaml))
  end

end

MailWorker

require 'zlib'

class MailWorker
  class_attribute :smtp_config
  
  def self.configure( options )
    options.merge!({
        :address              => "smtp.sendgrid.net",
        :enable_starttls_auto => true, 
        :port                 => 587,
        :tls                  => true,
        :authentication       => 'plain'
    })
    self.smtp_config = options    
  end
  
  @queue        = :mail
  @delayed_jobs = true

  def self.perform(options)
    Mail.defaults do
      delivery_method :smtp, MailWorker.smtp_config
    end
    comp    = options['message']
    message = Mail::Message.from_yaml(Zlib::Inflate.inflate(comp.to_s))
    message.deliver!
  end
  
end
