Actionmailer SMTP Server Response

Question

When sending mail through actionmailer, the actionmailer gets a response from the SMTP server, when its ok, or when its wrong. Is there a way to retrieve this response after

Answer 1

Looking at the the source you can define an observer:

in base.rb

  # Register an Observer which will be notified when mail is delivered.
  # Either a class or a string can be passed in as the Observer. If a string is passed in
  # it will be constantized.
  def register_observer(observer)
    delivery_observer = (observer.is_a?(String) ? observer.constantize : observer)
    Mail.register_observer(delivery_observer)
  end

So you could use some code like this in an initialization file:

class MailObserver
  def self.delivered_email(message)
    logger_info "Sent Message: #{message}"
  end
end

ActionMailer::Base.register_observer(MailObserver)

That will log sent mail and you can see if you can get the headers or response from the sent mail object.
