How to cancel email in delivering_email hook?

Question

I am implementing a email message queue. I use interceptor.

class MyInterceptor
  def self.delivering_email(mail)
    Email.queue(mail)
  end
end

ActionMailer::Base.register_interceptor(MyInterceptor)

But this code sends email in a normal way. How do I stop the email from being sent? I will manually send emails from the queue.

Thanks.

Set Mail::Message#perform_deliveries to false:

class NeverDeliverInterceptor
  def self.delivering_email(message)
    message.perform_deliveries = false
  end
end

ActionMailer::Base.register_interceptor(NeverDeliverInterceptor)

See API doc for source & other usage.
