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

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

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.

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
