How to send SMTP emails in background

My application sends emails with SMTP but I have a problem: It is very
slow, so every time my application sends an email it goes very slow.

I wonder if there is any kind of mode to do all the SMTP in background.
I mean, I would like to continue sending SMTP emails but I would like my
app not to go slow every time it sends an email. The app should do all
the business about sending the email in background.

Re: How to send SMTP emails in background

you''ve got at least two choices:

1) send your mail in a background process using backgroundrb
(http://backgroundrb.rubyforge.org/)
2) use ar_mailer (http://blog.segment7.net/articles/2006/08/15/ar_mailer)

backgroundrb requires you to run a separate backgroundrb process,
ar_mailer requires you to set up another database table for queueing
the mail, and then running a cron job at a specified interval to send
all the queued mail

Re: How to send SMTP emails in background

John,
	If you are on a linux system, pipe the email to sendmail instead. It
will take care of the queueing, etc for you and will send it by SMTP itself,
instead of your module having to rely on an SMTP connection. It looks like
ActionMailer::Base has a "delivery_method" option, if you set it to
"sendmail" it should just start piping them out via sendmail instead
of
SMTP.

Re: How to send SMTP emails in background

Another choice is to use the Ruby Thread. You can read up on it here

http://www.rubycentral.com/pickaxe/ref_c_thread.html

I''ve had great success using it with all my background processing
tasks. I just haven''t found a
situation where I needed backgroundrb, yet.

Re: How to send SMTP emails in background

In my case i used the Thread method.
In this example i use msmtp, and send my email via GMail.

In environment.rb

ActionMailer::Base.delivery_method = :msmtp

module ActionMailer
  class Base
    def perform_delivery_msmtp(mail)
      thread = Thread.new do
        IO.popen("/usr/bin/msmtp -t -C /etc/.msmtprc -a gmail --",
"w") do
 |sm|
          sm.puts(mail.encoded.gsub(/\r/, ''''))
          sm.flush
        end
      end
      thread.run
    end
  end
end
