Hello, I have the following in an observer:

    UserMailer.delay.msg_notification(record)

In user_mailer.rb class UserMailer < ActionMailer::Base ... def msg_notification(record)     mail(           :to => "#{record.user.email}",           :subject => "Notification"           )   end .. end

But this errors with:

NoMethodError (undefined method `delay' for UserMailer:Class):

Any ideas? thanks
