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.
