Looking for a way to deliver some of your ActionMailer notifications immediately (e.g. via :smtp) and others using a delayed/queued method (e.g. :activerecord using AR-Mailer (http://github.com/adzap/ar_mailer)?

Here's how I did it.

My default delivery method in my application was immedate using ActionMailer with SMTP.

# set delivery method to :smtp, :sendmail or :test


# or :activerecord for ar-mailer
 config.action_mailer.delivery_method = :smtp 

A corresponding model method action would look something like this;

 def deliver_new_registration_notice! 
  Notifier.deliver_new_registration_notice(self) 
 end

And for delayed (queued) delivery, you need to temporarily override the ActionMailer::Base.delivery_method;

 
 def deliver_existing_member_activation! 
   delivery_method = ActionMailer::Base.delivery_method 
   ActionMailer::Base.delivery_method = :activerecord #needed for bulk sending 
   reset_perishable_token! 
   Notifier.deliver_existing_member_activation(self) 
   ActionMailer::Base.delivery_method = delivery_method #reset it 
 end
